It may be more convenient to just tamper with the visuals of a command,
like
\version "2.22.2"
subx = #(define-event-function (fun) (ly:event?)
#{ -\tweak stencil #(lambda (g)
(grob-interpret-markup g
#{ \markup \concat { \with-dimensions #'(0 . 0) #'(0 . 0)
\right-align
\normal-text \italic "sub. "
#(ly:grob-property g 'text) }
#}))
#fun #})
subPP = \subx \pp
\score {
{
c'8\pppp\< d'8 e'8 f'8 g'8 a'8 b'8 c''8 |
c''8\fffff b'8 a'8 g'8 f'8\subPP e'8 d'8 c'8 }
\layout { }
\midi { }
}
Note that I put in some effort to stop "sub." from changing the
alignment. If that's undesired, removing
\with-dimension #'(0 . 0) #'(0 . 0)
should do the trick.
