crescendo and decrescendo within slurs

[Jin Choi]

I see that it’s possible to place textual marks inside of slurs: https://lilypond.org/doc/v2.25/Documentation/snippets/expressive-marks_003a-positioning-text-markups-inside-slurs

Is it possible to get crescendo and decrescendo marks within slurs as well?

\version "2.24.1"

top = { \change Staff = "upper" \voiceTwo }

bottom = { \change Staff = "lower" \voiceOne }

upper = \relative c' {

  \key g \minor

  \voiceOne

d'4.^\markup {\italic "espressivo"}^"a tempo"\p^- c8( d^\< f\! g^\> c,\!) |

}

lower = \relative c' {

  \clef bass

  \key g \minor

  f,16 bes \top d f 

      \bottom bes, d \top f bes 

      \bottom bes, d \top g bes

      \bottom a, c \top g' a |

\layout {

  \context {

    \PianoStaff

    \override StaffGrouper.staff-staff-spacing.basic-distance = #12

  }

}

\score {

  \new PianoStaff {

    \new Staff = "lower" \lower
