Firstly, I just want to say, what a staggering, immense and outright impressive update. Bravo!
I am working on a project with multiple percussion grids. Each player has their own bracket encompassing their entire grid - however - I wish to also have within each player’s grid sub-brackets, to help visually separate different groups of instruments (to help with ease of reading and to clearly identify actual physical placements of instruments - just one bracket for 11+ instruments is cluttered and it can be hard to immediately see what line belongs to which bloody thing to hit!).
I would make separate, smaller grids of the groups I wish to sub-bracket, and then combine them together as needed with brackets, and format the layout in such a way so that each part shows the correct instruments - but I frequently need to crossbeam / write chords or lines that jump across staves / lines in different instruments, which is impossible if they do not all belong to the same grid!
Please advise! Otherwise, I would love to see such a functionality introduced in a later update!
