Staff numbering

I’ve made a two arrangements of a piece which I’ve combined into a single file but it requires two different piano parts. The layout is no problem but how do I keep Dorico from numbering the piano parts? I can’t find where to turn this off.

The easiest way is to create a player group in the Players panel in Setup mode and put one of your two pianos in there; players in groups are numbered separately.

Ah yes, thank you, Daniel.
