Ah, I understand a bit more. As I interpret it, you want: A. The other characters not to have revealed areas from the previous session B. Her to have revealed areas from the previous session, and C. ALL players to keep revealed areas from the current session. In that case, in between sessions, reset the Advanced Fog of War on the maps in question. Retrace her token through the areas already explored before putting the players on that map. As I understand AFoW (caveat—I don't use it), that should accomplish those goals. Though it would require a bit more time in setup, it's less work than maintaining separate maps. There is an API that can run tokens on separate maps at the same time, I think it would ultimately be more work and more confusing for a feature you are likely to use a lot.
