Can you "wait" in Imbroglio?

Can you wait a turn in Imbroglio without moving or do you always have to move or attack?

If not, is there any way to simulate waiting via a tile power or movement strategy? For example, I noticed that if you block the door when a new monster first peeks out, they effectively lose their turn (they don't move out or attack) and you end up next to them, which is usually what I want.
