Copying/Pasting between percussion players

I notice that we can copy and paste between a pitched instrument staff and a percussion staff, and Dorico uses the relative pitches to “guess” at where to put the notes in the percussion staff. But I can’t copy rhythms from a percussion staff and paste that into another percussion staff with different instruments in the same way. That would be very helpful when writing for multiple percussion parts.

See if switching to individual single-line staves for each percussion instrument temporarily while you copy and paste before you switch back to your normal grid will help.
