In other words, is something like this possible?

\version "2.22.1"

Dynamics_mover_engraver = FOO

piano_upper = {
  c'4\p d' e' f'
  g'1\mp
  g'4\f f' e' d'
  c'1
}

piano_lower = {
  \clef bass
  c1
  g,1
  g,1
  c1\ff
}

\score {
  <<
    \new PianoStaff <<
      \new Staff \with { \consists Dynamics_mover_engraver } \piano_upper
      \new Dynamics #(skip-of-length piano-upper)
      \new Staff \with { \consists Dynamics_mover_engraver } \piano_lower
    >>
  >>
}

where all the dynamics in either of the two Staff contexts would appear in the 
Dynamics context instead?

Thanks,
Kieren.
