Timbre change while sustaining note

Am I correct in assuming that everything in the lower, "output," section of Pianoteq can affect sustained notes in real time (hold a note, move a slider and the sound changes as the note is held)? And nothing above "output" (tuning, vocing, design) has this functionality?

I would love to see the ability to, say, change unison tuning of a sustained note, so if that parameter were assigned to an expression pedal, we could detune a unison while sustaining a note. I'm not sure what programming adjustments this would entail, but it would be great if every parameter had this functionality. It would be particularly useful for the "spectrum profile" and other parameters that would make a big change to a sustained note's sound.
