Apparently brackets for shared fingerings, i.e. when you press down two strings with one finger, aren’t available for guitar. This is not the same as a barré, and I’d like to indicate it more clearly than just by adding the same finger number:
The existing 1/2C is cumbersome and cannot be added next to noteheads, and not precise enough.
I’ve found a bracket that almost does the job in ornaments, but doesn’t work properly across different voices, it puts the bracket around all the notes rather than just the two I want.
I’d really appreciate the feature!
