Engraving Options allows Staff labels to be grouped for Solo Players,
but not for Section Players.
I know I can use Divisi, but that seems cumbersome for Violin I and II (which each might want separate divisi options later). And Parts wouldn’t work.
It is common for Violins to be labelled as a group. This came up in discussion with people trialling Dorico, who considered it a ‘dealbreaker’.
