Hi Valerio,

you cant do that directly in the location plugin, but it is quite easy to 
extend that plugin to do what you want.

basically, you create a new plugin, lets call it MyProjectLocation

the template would look like this:

 * @package CorePlugins
 * @version $Id: ClientMyProjectLocation.php,v 1.8 2005/02/23 11:52:43  Exp 

class ClientMyProjectLocation extends ClientLocation {

    public function replacePlugin() {
        return 'location';

    // here redefine the function you need, most probably drawShortcuts() 
/**     * Draws shortcuts form     * @return string     */    protected 
function drawShortcuts() {        $this->smarty = new 
Smarty_Plugin($this->getCartoclient(), $this);        $shortcutValues = 
array(-1);        $shortcutLabels = array('');        $shortcuts = 
$this->shortcuts;        if (!is_array($shortcuts)) $shortcuts = array(); 
/* do what you want with the array containing the shortcuts, list spliting, 
sorting, etc....             below is the original function code, allowing 
to treat the shortcuts values and labels */        foreach ($shortcuts as 
$key => $shortcut) {            $shortcutValues[] = $key; 
$shortcutLabels[] = I18n::gt($shortcut->label);                    } 
/* now let say you cuted your shortcuts in 3 arrays (hence 3 for values and 
3 for labels),         you assign them to your template vis smarty */ 
/* below the original code */ 
$this->smarty->assign(array('shortcut_values' => $shortcutValues, 
'shortcut_labels' => $shortcutLabels));        /* you would have to do 
something like this */ 
$this->smarty->assign(array('shortcut_values_1' => $shortcutValues_1, 
'shortcut_labels_1' => $shortcutLabels_1, 
'shortcut_values_2' => $shortcutValues_2, 
'shortcut_labels_2' => $shortcutLabels_2, 
'shortcut_values_3' => $shortcutValues_3, 
'shortcut_labels_3' => $shortcutLabels_3));        return 
$this->smarty->fetch('shortcuts.tpl');    }    /* you will also have to 
redefine the function handleShortcuts, because only one input (select) can 
have one id,     so you need to tell the plugin to treat the value returned 
by these inputs too */    protected function handleShortcuts($request, 
$useDoit = true,                                                  $check = 
false) {        if (isset($this->getHttpValue($request, 'shortcut_id')) 
{            $shortcut_id  = isset($this->getHttpValue($request, 
'shortcut_id');        } else if (isset($this->getHttpValue($request, 
'shortcut_id1')){            $shortcut_id  = 
isset($this->getHttpValue($request, 'shortcut_id1');        } else if 
(isset($this->getHttpValue($request, 'shortcut_id2')){ 
$shortcut_id  = isset($this->getHttpValue($request, 
ut_id2');        } else if (isset($this->getHttpValue($request, 
'shortcut_id3')){            $shortcut_id  = 
isset($this->getHttpValue($request, 'shortcut_id3');        } 
$shortcutDoit = $this->getHttpValue($request, 'shortcut_doit'); 
if (is_null($shortcut_id) || ($shortcutDoit != '1' && $useDoit)) 
{            return NULL;        }                if ($check) { 
if (!$this->checkInt($shortcut_id, 'shortcut_id'))                return 
NULL;                            if (!array_key_exists($shortcut_id, 
$this->shortcuts)) {                $this->cartoclient->addMessage('Shortcut 
ID not found');                return NULL;            }        } 
$bboxRequest = new BboxLocationRequest();        $bboxRequest->bbox = 
$this->shortcuts[$request['shortcut_id']]->bbox;        $locationRequest = 
new LocationRequest();                        $locationRequest->locationType 
= LocationRequest::LOC_REQ_BBOX; 
$locationRequest->bboxLocationRequest = $bboxRequest;                return 
$locationRequest;            }}?>

and in your shortcuts.tpl simply put the smarty variable $shortcut_values_1
 $shortcut_labels_1 $shortcut_values_2 $shortcut_labels_2 $shortcut_values_3
$shortcut_labels_3 as needed

 <select name="shortcut_id1" id="shortcut_id1"
{html_options values=$shortcut_values_1 output=$shortcut_labels_1}
 <select name="shortcut_id2" id="shortcut_id2"
{html_options values=$shortcut_values_2 output=$shortcut_labels_2}
 <select name="shortcut_id3" id="shortcut_id3"
{html_options values=$shortcut_values_3 output=$shortcut_labels_3}

Finally, dont forget tp load your new plugin. In the file 
client_conf/client.ini add it to the loadPlugins list

That should cover most of it.
