[Creation Kit] Simplest way to create a ForceGreet in a Quest Scene?

[Nexussux!]

What could be the simplest way to make an NPC enter the conversation with the player (or vice-versa) that you can think of?

 

I.e. "Phase 3" - Action 6: SpeakToPlayer (force greet happens here)

 

Note that it is the matter of simplicity, NOT ease of implementation (though two might not be mutually exclusive). The less steps/scripts the better - for compatibility's sake. Thank you!
