Separate autosaves per game

I've noticed a lot of RPGs have changed how they handle savegames in the last few years and i'm wondering if ES2 could benefit.

Essentially, they divide each playthrough into its own set of savegames (in an RPG this is by character.)

It might be tricky to implement at this stage, but it would be awesome to have Endless Space 2 treat each game as a separate set of savegames, including having its own autosaves.    It would especially help out folks who juggle MP and SP games.
