Allow syncing across roots, ie multiple instance of the same game

[Pablo1107]

What's your idea?

What do we do if you have the same game installed in multiple places? For example, I have three copies of Dead Cells, and these are their save locations for the same file:
C:/GOG Games/Dead Cells/save/user_0.dat
C:/Program Files (x86)/Steam/userdata/123.../588650/remote/user_0.dat
C:/Users/mtken/Games/Heroic/Dead Cells/save/user_0.dat

Based on this comment, something that I think would be useful for some users would be to sync across different instances of the same game and have all of the share the same "save file" by backing up and restoring it on launch or have some kind of dialog where you ask the user which save file would like to keep, from which root.

In my use case I have two versions of the same game and I would like both to by in sync. Don't know if this this would something that could be implemented as part of Ludosavi.
