Photoshop: Slice Comps that work like Layer Comps

Layer Compositions are very handy to manage huge amounts of layers in one file e.g. if your working on screen interface layouts. You work on your layout, save this arrangement of visible/invisible layers in a Layer Composition and you can work straight away on the next screenlayout with a different arrangement of layers in another Layer Composition.

Additionally Photoshop has the great feature of Image Slices.
You cut your document in smaller assets and export them in one single step. This works great together with Layer Compositions.
As soon as you have lots of overlapping Slices, it becomes a mess and is very painful.
You have to arrange them new, you don't see them, because they are in background and so on...

So here is the simple, but timesaving idea:
Add Slice Compositions that work exactly like Layer Compositions.
Or better and simpler: Combine Slice Compositions to Layer Compositions.
Simply save the arranged slices in a Layer Composition.

This feature could become a enormous timesaver for designers.
Imagine if you could export all your assets of all your screenlayouts in one single step ...
