Custom VSTi?

I downloaded the deno version of Notion 3 and have about 7 days left. Though I'm amazed at how simple it can be to set up a score I can't figure out how to make articulation changes. I've been trying it out with UVI Ircam Solo Instruments. I load flute articulations such as staccato, crescendo, flutter-tongue etc.. but I can't figure out how to switch from one to the other. I sense that I'm supposed to create a staff for each articulation in "score setup" & then assign them to channel one (flute). I don't know how to do this, however. Any help would be appreciated.
