Not really, the contents of the saves will depend on your choices and routes during each week, which will affect what happens in the story as you go along. Pre-simulating a save would assume you made certain choices etc in the prior week, which if you have made different decisions to follow a certain path, it would not match up with what you'd done in the previous week of the game (nor for many other players).Wouldn't simulating a save before the start of every week be a better solution, than requiring previous saves??
So it's better to have the information of your prior choices/path, than forcing them on everyone who may have made different ones.
