I'm not 100% sure I understand what you're saying, but keep in mind that
ka-Map generally is going to generate *one image* for your group of
layers (unless you're in a different situation than I have used ka-map
in the past). If you have a layer pre-cached, you have a number of
images with all the data in those images -- you can't change a single
layer in those images without regenerating the whole thing.
But maybe you're looking at something else and I'm just crazy. It
wouldn't be the first time.
