X50 Can you Delete a Room?

All of a sudden my X50 has added three “new” rooms (????) how do I delete these… the put them “to the side” of my regular rooms so after the robot is done cleaning it comes back and re-does the new rooms which are my regular Living Room, bathroom and office.. can I just delete these rooms or do I have to delete the entire map and have it do a whole new one?

I would say to delete the current map and remap the area.
