Any way to change autosave in game?

[Neo]

Just had a game crash after playing three hours with no manual saves, so I lost all those turns. Never had SEIV crash on me before, but I haven't been playing that long, so I left the Autosave option on None when I created the game. I want to keep playing this game, but now I am paranoid the game is going to crash, so I want to autosave so I don't have to save manually all the time, but it appears that the autosave option is only available on new game creation. What was the reasoning behind that? I wish it could be changed in game. Another thing to add to my wish list I guess.
