What is the event id to make courtier or lord a dragon rider

Does anyone one know the event id to make a charector that is not you a dragon rider so it also spawns them a dragon as well. I tried to add the dragon rider trait since it spawns the players charector a dragon but it doesn’t work for Courtiers or other lords. So I’m guessing the event only triggers if you control them so I am hoping if I enter the event via council command for that charector and that might make it work. Right now the only way I have been able to do so is by using the dragon tamer laws submod and making them a friends or making them part of my dynasty first and giving them the dragon that I spawn myself but that takes quite awhile and involves save game editing. So I was hoping there is an easier way since I like to make custom scenarios when I play. Or if you know another easier way please let me know.

thanks
