Continued guitar fingering with horizontal lines

Your idea

In guitar notation, it is common to indicate continued string designations (circled numbers 1 to 6) with a horizontal line.

Here from Behind Bars by Elaine Gould, p.374:

Similarly, continued right-hand fingering (italic letters p,i,m,a) can also be indicated with a horizontal line (although a bit less common).

Again from Behind Bars, p.374:

Problem to be solved

This allows standard guitar notation without repeating the same fingering for each note, adding visual clutter to scores.

Additional context

This should be quite easy to implement since horizontal lines with start text are already available in MS.

The problem is the formatting: start text cannot be formatted. This is important for string designations (text must be circled) and right-hand fingering (text is small and italicised).

Start by locating MuseScore’s existing horizontal-line implementation with start text and its text-formatting path. Check how circled string designations and italic, small right-hand fingering are represented. Done when both types of fingering can continue across notes with their required formatting without repeated text.
