Allow setting notehead scheme on a note-by-note basis in the Inspector
Currently one can assign a notehead scheme to a staff only. Using staff change elements, this can be achieved on a per-measure basis.
In educational scores, it is not uncommon to only use the named notehead for the first occurrence of a given note; something currently not possibly within MuseScore.
The idea is to allow setting the notehead scheme on a note-by-note basis using the inspector.
A possible easier in-between step would be to at least expose those notehead symbols within the current listing (as is already the case for 7-shape noteheads). The downside there is that the notehead doesn't automatically update when the pitch is changed; but it would allow us to create the desired end result without having to resort to the symbols pallet (and manual placement involved in that workaround approach)
