Unassigning polys from custom surface groups

mtl1

Like the title says, is there a way to unassign polys from surface groups? I'm trying to kitbash some old content, and the part that really holds me up is that I cannot seem to find a way to unassign polygons from a custom surface group. Not only that, but undo doesn't seem to *unassign* them and instead shows 'undo polygon selection'.

As an aside, is changing the surface group's opacity or hiding polygons the preferred way to hide things?

All polygons have to belong to a surface and a group - so to unassign them to one group you have to assign them to another. Not having the assignment added to the undo stack, however, would be a bug as far as I know so please report it.
