Create multiple save states for campaign

In the long-term, I would love the ability to save a campaign at different points and be able to return to previous save points (e.g., if something unexpected happens and the entire party is wiped out). As a short term option, maybe having a “clone” campaign option would also do the trick. Even though you can use the “delete to here” option currently with Franz, this does not revert back to previous stats, or character configurations, like a true save state would.
