Hello! A friend of mine asked if I could make him a score with arrow indicators and a bifurcation/splitting of a staff. I'm aware of the "Adding indicators to staves which get split after a break" snippet and I am very fond of it. However, I could not match what this friend is requesting; I've only managed to write ossia staffs that create extra space on a score.
Is there any possibility of doing something like this picture below? On top is lilypond's default output and on the bottom is what I seek to write.
Best regards,
Lucas
