Move direct bookings

I would like to move guests from one unit to another more easily. I can alter the date of a stay, but I can't find a way to change the unit.

There are times when something goes wrong and the easiest way to fix it is to offer a better unit to a guest.

Since it's a direct booking we do a deposit, so if I have the guest cancel and book anew there's lots of extra transactions.

I really want to be able to "Alter the booking" and let the location be one of the things I can change.
