Instrument name that's visible in full score only

In my full score, I have an instrument named “Piccolo (opt.)” which is the way I want it to show in the conductor’s full score:

But when I look at the individual part score, it also shows up as “Piccolo (opt.)” which is…ummm…I don’t really want to give the piccolo player a complex:

Is there a way to add text like this to the instrument name, but not have it show up in the part?

yes, that’s possible.
The “part” name in Dorico refers to the Layout Name. In Setup Mode go to the right panel and change the Layout Name to your liking.

Perfect, thanks so much!
