Dynamics for both staves

[Paulo Matos]

Hi,

I am trying to apply dynamic marking like piano and so forth to both
staves.

I have the following example:

\version "2.25.2"


right = \relative c'' {
  % Music follows here.
  c2\p d4 e
}

left = \relative c' {
  % Music follows here.
  c4\p e g r
}

\score {
  \new PianoStaff \with {
    instrumentName = "Piano"
  } <<
    \new Staff = "right" \with {
      midiInstrument = "acoustic grand"
    } \right
    \new Staff = "left" \with {
      midiInstrument = "acoustic grand"
    } { \clef bass \left }
  >>
  \layout { }
  \midi { }
}



In this case, both piano markings show up under their respective staff
but it would be much nicer and as far as I understand it, how's it's
usually done, to show up between staves.

I have seen the following solution:

\version "2.25.2"


right = \relative c'' {
  % Music follows here.
  c2 d4 e
}

left = \relative c' {
  % Music follows here.
  c4 e g r
}

\score {
  \new PianoStaff \with {
    instrumentName = "Piano"
  } <<
    \new Staff = "right" \with {
      midiInstrument = "acoustic grand"
    } \right
    \new Dynamics {
    s1\p  
    }
    \new Staff = "left" \with {
      midiInstrument = "acoustic grand"
    } { \clef bass \left }
  >>
  \layout { }
  \midi { }
}


i.e. start a new group called Dynamics and add the dynamics there but
this seems suboptimal as it makes the typesetting separate from the
notes _and_ as far as I understand it, doesn't affect MIDI - and the
first solution does.
Is there a better solution to this?

Thanks,
