Trigger if you or your vassal owns a province

[fixmypcmike]

Is there a generic way to have a trigger condition which is true if you or one of your vassals own a province?

No, there is currently no way to base a trigger on a vassal. It's possible to do it the other way around (have a trigger condition which is true if you or your overlord own a province) and then trigger something based on that, but that's a bit messy.
