Of course there will be a command like that. However, it makes more sense to me to have it automatically ask you about calling an Elevator when you walk up to an Elevator Door, or, if there is no Elevator Door on that floor, by pressing a brick button using v9's event system. By doing it that way, the experience can be much more natural. I don't like to burden the user with having to use /commands, but they are there if they prefer. I find myself using /commands a lot, but that's just me.
