How can i change my Faction heirs without the AI assigned one getting the disinherited trait once i strip him of his title, and give it to my most favoured general........ b'cos sometimes the ai gives it to a governor, who's nice and cosy behind the city walls, while my good generals deprived of the privelige of becoming faction heirs, and then faction leaders.

can it be done??? i even tried changing the heirs on the turn they were given the title but still the disinherited trait appears to the person whom i stripped it from..............
