scratch pad like studio one style

well this FR is already mentioned in cubase 9 forum,maybe here too, but i want to bring it up here again,cuz i also didn’t see this option on the August FR pool
many times me and my clients change the project ,(different intros,endings and so on) and put aside the ideas on the end of the project to save them for later use if needed or create new copies of the project.well this is a mess.
