Control head rotation with matinee?

I’m adding custom skeletal mesh actor to use it for characters in matinee cinematics and automate some behavior. Can’t figure out how to set up head control. Normally, I would use AnimNodeAimOffset and update it with scripts. Unfortunately, there are no way to update this node from matinee directly. Using skeletal controllers for each bone would be difficult because matinee can only update their strength, not their values. Any other ideas?

Use a kismet node ? mmmh idk idk

Kismet or scripts would require to launch the game to see changes. I’m looking for a way that would display head rotation in matinee.
