MapLab does support adding a virtualspatial layer.  For more help on 
virtualspatial connections send a note to the main mapserver list.  Here 
is a sample layer pointing to an access database:

   LAYER
     CONNECTION "<OGRVRTDataSource>
<OGRVRTLayer  name='test'>
<SrcDataSource>ODBC:CDD</SrcDataSource>
<SrcLayer>mytable</SrcLayer>
<GeometryField encoding='PointFromColumns' x='LONG_E' y='LAT_N'/>
<GeometryType>wkbPoint</GeometryType>
</OGRVRTLayer>
</OGRVRTDataSource>"
     CONNECTIONTYPE OGR
     DATA "test"
       METADATA
         "wms_srs"   "EPSG:4326"
         "wms_title" "test"
       END
     NAME "test"
     PROJECTION
       "init=EPSG:4326"
     END

         SIZE 6
         SYMBOL "square"
       END
     END
   END

This is a general mapserver question and should be asked on the main 
mapserver list 
(http://lists.gis.umn.edu/mailman/listinfo/mapserver-users).  Also see 
the mapfile documentation for a description on the GROUP parameter 
(http://mapserver.gis.umn.edu/doc42/mapfile-reference.html).
