Create a \prall with a slur above

[Viktor Mastoridis]

Hello,

I would like to create an upper mordent (\prall) for guitar tabs, which would have a curved slur over a single note.

The reasoning is that I would like to distinguish the regular Mordent (where each note is plucked), with the Grace Mordent (where the first note is plucked, the upper note is a quick hammer-on and the lower is a pull-off)

(See attachment for a more detailed rendition; or the image)

So far, I came to this construct:

\version "2.20.0"
\new TabStaff  { \tabFullNotation
g\prall ^\markup { \path #0.2 #'((curveto 0 -0.5 0 2 1.5 0)  )} }

I wonder whether there's a more elegant solution?
