Or are they only possible to attach to staffs?
I’m arranging an orchestral score now, where there’s a soloist (indian) improvising. I’ve made some modules that I’d like both the conductor and all performers (in the parts) can have the same lines (horizontal brackets mostly) showing excactly what the individual modules are. But as for now these lines only apply to the top staff. Is there any way to make these lines “system attached”?
I know some other solutions to the problem (system text, repeat bar lines etc), but I’d love to find a line-solution for future cases.
