If you want marks aligned on the same level exactly, why not put them in
the same markup altogether?

\mark \markup { \bold A some more text }

Then you don't need the multi-mark-engraver.

Sorry, I wasn’t clear. The alignment to the same level is in order to get them aligned to the chord symbols. If I have several marks at the same time, they might very well be not level. I’ll need them as separate marks to be able to process them separately. There might be situations like one mark appearing before and one after a line break(, but at the same point in time in the code).

Okay. Here is a version of the engraver that caters for this case. I've also cleaned it up somewhat.

Let me know if you encounter any issues with it.

Thank you. It fixes the error, so the score at least compiles again. But it sadly also renders my use of \override RehearsalMark.outside-staff-priority = ##f useless. (Compare in my original example the output with that line commented in and out.)
