I recently bought an upgrade for the door on the 3rd story of my house, and then (because I'm fickle, I admit it) decided it would work better on the 1st floor. I can't get the door to change floors, and I think I'm stuck with the upgrade on the door on the floor I upgraded it on. Is there a way to swap doors between floors? I don't think one upgrade should lead to four doors being upgraded, but it would be nice to be able to swap one upgrade between floors.
