Stupid question of the day - Articulations

In an effort to reduce the number of instruments in my template, I have decided to start using Keyswitched instruments.  So I have defined Articulations in Synfire no problem.  But how do I actually assign them to a phrase or a note?

The only Controllers that show up for me are program changes and the normal stuff (see pic) in the phrase editor.  If I manually have to add the note in after I assigned it seems counterproductive.

I know it's probably simple but I haven't used keyswitches up to this point in Synfire.

Thanks,

Brian
