Very well!!
You can do it from scratch OR you can harvest some maps from here to there, using only that you need, for example, I remember saw a scene in Kenzato booru of a stage, crowded and then the couple gone to the toilets to have some action, so you can use that scene, clearing all actors, folders with gimmicks, lights, props etc, and save that scene. then Import only the necessary, for example only the stage, right. then search another scene and "borrow" the bar, tables, props, and so. You feel me?
