Distributing Titles

I don't believe there is. The closest thing to it is just having one of your councilors hand out extra titles for you, but as they may hand out a title you don't want handed out that may not be the best thing. I've always just done it manually myself. That way I can pick who gets what for a more stable transition for the realm. I usually use the character finder and narrow down the number of characters by using the filters (same religion/religion group, same culture/culture group, lowborn, not a ruler, etc.) and if wanting a certain trait, i.e. content or honourable, then type that into the search box. I also sort the list by how much they like me or by one of the stats if I'm looking for a character that utilizes that stat. If I'm looking for them to try and convert the province to my religion then I'll search for zealous characters of my own religion.
