When I pull a game up from my archive, it's one of the choices. Ok, it may take a minute or so for the game to show up in your archive after finishing, but that shouldn't matter. This is from V2.

Is there a way that you can do this that I don't know about? I, probably like some other people, feel that my end game can always improve, and I never get the chance to work on it if people resign against me before the end game stage takes effect.
I know it's possible on the mobile app to do it, but if there was a way to do it right away on PC after a game ends, that would be fantastic.
