carve/delete/bridge brush for sculpting

hi guys.
sorry to post this one here but i don’t really know where to post it.

basically i have a feature request for sculpt.
i need to model thin layers of cloth with holes in them.
would be nice to have a brush that actualy erases polygons.
if there are polys in the back side of the mesh then deletes
them too and bridges the two opposing faces together.
hard to explain, pic sez it all.
with one click i would be able to punch a hole into my mesh.

currently my only way to achieve the same effect is to exit
sculpt mode, enter edit mode and yada, yada, yada…you guys
know the drill.
it would be nice to NOT have to go out of sculpt mode for this.
