Checking character names in trait triggers?

Is it possible to check a character's name in a trait/ancillary trigger?

I've had a little play with the traits and would like to try to implement adding numbers to faction leaders (King Henry II, etc).

I don't think so. Can't find it in the docudemon anyways.
A possible workaround (player characters only) would be to trigger on character selection, because I_CharacterSelected takes a character name as a parameter.
