Unfortunately, I can not catch your idea, which you want to convey to me.

In what program and in what place do I need to "Go to the state before..."?
I work and modeling exclusively in MOI3D.

If this is feasible in MOI3D, then I would appreciate your clarification.
It would be cool if you somehow noticed this visually. Thank you!
