Is it possible to change a King's Child

[Max2150]

I am making a mod in which a few of the factions are based on real historical figures. However, during the game, the leaders of the factions are assigned random 'children' I believe. This kinda breaks my immersion when one of the faction leaders doesn't have their actual son as a child, instead he has another lord as his son.
Is there a way in which I can specify the child for certain Lords, or do I have to leave it totally random?

Thanks - Max

you can use the Q&A thread for quick questions

script "game_start" runs the code when creating a new campaign. One of those steps is the setup of nobles, which is under the sub script "initialize_aristocracy"
