If you want to change the visual contents around a multimeasure rest (easiest changed in Scroll View), this information may be of use:
- Entries that aren't note-attached (such as measure-attached expressions and text blocks) are displayed at the multimeasure rest if they are attached to the first measure in the region.
- If you want to change the barline after a multimeasure rest, you have to change the barline after the last measure in the region.
