Invisible/cutaway floor tiles

I frequently modify the DAM files to get more options, but it would be really cool if there were an invisible/transparent see through floor tile for rooms so I can see the objects I sink beneath the floor. It would save a lot of time because I wouldn't have to move as many tiles out of the way. It will likely be a while until the next update for multi level buildings. This would me nice in the mean time and also in addition to.
