Preserve Chat in Saved Games?

Is it possible to get the in game chat stored in the save file? I play a lot of split games of Twilight Imperium 4. The mod does a great job chronicling every action in the game so it's easy to go back and check if you forgot something or whatever. But since we play in 2 hour chunks weeks apart, that chat gets reset every session.

Is there a way to keep it from game to game?
