Multiple levels in same room

Hi there. I need an advise.
The game im making is quest that takes place in one small room with many items in it. It was all nice until i realized that there is too much blueprints, matinees, cameras and so on in this room — so i decided to split game in multiple levels whitch will represent game days. But if i do so, every change in one room i should copy to all other, and thats weird.
How would you do multiple days in one room game? Should i keep anything in one level? Or is there some trick for situations like this?
