Ok, is there anyway to do this? That is, I have made a few attempts to clear out some rebel uprisings, in some of the provinces where I can see the rebels about to clear out another faction. I'm not willing to allow this now as it's my JOB to clear out other factions down the road. So, I pop in, knock out the rebels, start the chase, etc.

Is there a way to hand over the lands back to the beseiged army that I didn't attack? When if I went after another faction in lands that I currently do not want (high costs, rebels, etc.) just to clear out their armies, is there a way to hand it over to another faction?

I've heard some talk of autoceasefire. What is that? is it just a concept of self control from attacking another faction, or is it a real thing?
