Feature Request: Save multiple Snap-to-Scale settings

[jimlynch22]

If Snap-to-Scale settings could be saved at various HH:MM:SS in the project, similar to how articulations are save for each track, it would really help writing melodies in the PRV. To simplify, they could be saved like tempos, applying to all tracks.  Applying on Snap-to-Scale setting across all tracks which would be a more usual usage, having all tracks snapping to a single scale.
