Is it possible to change the vertical space between the two staves of a PianoStaff on a single line? I get how to do it for the entire context, you simply put "\override StaffGrouper.staff-staff-spacing.minimum-distance = #number" in \with of the pianostaff, but I would just like to do it on a single line. I thought \override at a certain point would work but it does not.
Thanks,
