Would it be possible to add the ability to tell AI allies to go and take a settlement that you have razed, if it is not something you want to hold onto?
Example - I'm Empire, and don't have the desire to deal with the negatives of uninhabitable mountain holds, but the dwarves are being pushed hard and losing ground. It would be nice if I could point to a mountain ruin and say, "Yo, go take that thing," which keeps the skaven from settling it while I'm not looking, and also helps prop up my little buddies.
Because God knows, they wont do it on their own.
If we cant cede territory voluntarily, this would be the next best thing...
