I know that de jure kingdoms and empires held by rulers of certain cultures(i.e: turkish, berber, levantine) have the name and coat of arms of the ruling dynasty. Same thing with patrician houses. I also know that you can do the same in titles (i.e: " dynasty_title_names = yes")
I know this is a tricky one, but is there anyway of making it so that baronies, counties, duchies and kingdoms have the *coat of arms* of the ruling dynasty, while keeping the original name? This would be historically accurate somewhat, and would save me quite a lot of work on my mod. Since somethin similar is in the game I imagine it might be possible.
