Implement Flexible Parameters for Choreographing Percussion

Alfred Blatter's excellent book: 'Instrumentation & Orchestration', includes a hyper-useful section on choreographing percussion instruments.

MuseScore could make it easy-peasy to convert percussion parts organised by instrument, into percussion parts organised by player. Thus a score could be imported (or made) showing percussion instrument names down the side, for the user in MuseScore then to organise these into Percussionist down the side (Perc. I, Perc. II, Perc. III) and drag instrument parts into them block by block, with clef and instrument change being set automatically.

At the MuseScore Handbook here:

https://musescore.org/en/handbook/mid-staff-instrument-changes

…it says:

‘Mid-staff instrument changes are limited to the same type of staff. For example, you cannot change between a percussion staff and a pitched instrument staff or vice versa.’

…by definition, percussion instruments can be unpitched and pitched! (ii) Why shouldn’t a player be able to switch from a shaker to a xylophe mid-score?

The above facility would be very, very cool. :o)
