I think you know what I mean! sigh, maybe you don't.

ok *cough *cough* so what I'm trying to say is that I made this room which is a hallway leading to a door with a room inside. but I want to move that room to make it a little down, so I can make stairs, but when I select that room then some of the other rooms/hallways gets selected too and I don't wan to fix everything then! and it will ruin my lovely, beautiful, handsome, awesome, cool... etc map! is there a way to select that room without selecting something else with it? pretty pls! puppy face if you don't like puppies then kitten face if you don't like kittens then I don't know!

but is there a way to do that
