Setup Mode: ensemble player reassign intrument problem ...

… i.e. this does not work. I can reassign the instrument for all solo players, but not for the complete string section with ensemble players. The reassign dialogue window does not open.
(This happens in an “old” Sibelius imported score, and I had to reassign all instrumens to get condensing working. But just “to be sure” I wanted to
reassign also the string section to have a clear start for engraving tasks, so I found out that it does not work.)

Indeed, you cannot currently use Change Instrument for a section player.
