I'd love this to be featured. I like to create dynasties in my playthroughs, and as such it means I typically have over 30 children/grandchildren/Greatgrandchildren that will focus on specialties. Fx. Governors/Horse Archer/Cavalry/Infantry/Archery.
I'd add it to their names, but this breaks my immersion. A customizable note next to their names in the dropdown menu of the Character tab would be ideal.
