Like many other things, there is an easy work around (using first-stave indents and text boxes) however as is common in organ music, it would be nice if you could name the stave labels for Manuals/Pedal separately. Currently Dorico shows “Organ” for all 3 staves. There is no doubt that this is a good starting place, but in the setup menu I couldn’t figure out a way to label the pedal and manual staves separately. I was able to do this in one score that I had imported as XML and thus the manuals and pedals showed as two “instruments” for my organ “player”. But that is the singular instance where the option has been presented in a native manner.
