Settlement occupation design

Jxarl#3036

One thing I've noticed is that when you occupy a settlement outside of your desired/starting zones, the settlements graphics and design is kept as the previous occupiers faction. If for example I am playing The Empire and am taking over a Tomb King settlement, id like it to look like an Empire Settlement and not a Tomb Kings Pyramid. Or if that's not a desired visual direction for the campaign, maybe just add some more faction elements (not just flags) to the occupied settlement instead of a complete change. In my opinion this would add to the visual experience of the Immortal Campaign.
