Dorico already places the word “div” and “unison” at that place as it is for the Divisi change…so its kind of redundant to place another word saying the same thing, just to trigger the keyswitches. Plus its something I have to remember to do, otherwise the playback will be wrong. But I get your point. I guess I can hide them. I was just wondering if there was another way to cause Divisi change to register itself as a playback technique, but sounds like not.
I think you can hide them using Properties
