Suggestion: QOL favoured maps per atlas tree

Really small QOL but would save some time.
Right now favoured maps are global, when switching between atlas trees, your favoured maps stay the same.
This is likely fine for many players, but On my Destructive Play tree I also run Shadow Shaping. so whenever I switch to a different tree I need to redo all my Favoured maps.
Again this is a really small problem, but seems like a good fix to save players small amount of time each time they swap atlas trees.
