Adjust system-crossing melisma's vertical position
Manual vertical positioning of any element may be necessary to avoid collisions, and this is especially true for lyrics. Melismas are attached to their preceding lyrics and, as a result, also gets their vertical offsets. This makes sense within a system, but if the melisma crosses to the next system, a user may want this melisma in a different position relative to the staff, not just to save space, but to align with the lyrics in the new system.
The use-case for this is best shown with an example.
There is currently no way to get the score with System 1 of the second page and Systems 2-5 of the first.
