There should be a backboard that can be placed on the wall to fit any trophy, people can place them where they want on the wall. Then this way, trophies can be swapped in/out remotely, without the need to actually travel to the house and hit the build screen. This is because the trophies will be placed on these backboards frames randomly.
There’s also the ability to place them on the wall, in case people want permanent placement, such as a cooking trophy in the kitchen area. These cannot be swapped out.
