Rotate Rooms Underground

It would be an excellent addition if we could do the same things to rooms placed at floor 1 and above in terms of rotation, height adjustment and non-flat rooms.

Currently however, none of these options are available once your map goes to -1 or below in terms of room placement. I am unsure if this is a bug, or a feature that has not been developed yet, but either way. It’d increase room variety a lot.
