Here is my attempt at automating it.

\version "2.22.1"

\layout {
  \context {
    \Score
    \consists
      #(lambda (context)
         (let ((tempo #f)
               (mark #f))
           (make-engraver
             (acknowledgers
               ((metronome-mark-interface engraver grob source-engraver)
                  (set! tempo grob))
               ((mark-interface engraver grob source-engraver)
                  (set! mark grob)))
             ((stop-translation-timestep engraver)
                (if (and tempo mark)
                    (begin
                      (ly:grob-set-parent! tempo X mark)
                      (ly:grob-set-parent! tempo Y mark)
                      (ly:grob-set-property! tempo
                                             'X-offset
ly:side-position-interface::x-aligned-side)
                      (ly:grob-set-property! tempo 'Y-offset 0)
                      (ly:grob-set-property! tempo 'side-axis X)
                      (ly:grob-set-property! tempo 'padding 0.5)
                      (ly:grob-set-object! tempo 'side-support-elements 
'())
                      (ly:pointer-group-interface::add-grob tempo 
'side-support-elements mark)
                      (set! tempo #f)
                      (set! mark #f)))))))
  }
}

{

  r1
  \mark \default
  \tempo 4 = 120
  \time 3/4
  \repeat unfold 4 c''4
  r1
  \mark \default
  \tempo 4 = 120
  r1 r1
  \mark \default
  \tempo 4 = 120
  \repeat unfold 4 c''4
  r1
  \mark \default
  \tempo 4 = 120
  \repeat unfold 4 c''4
  r1
}


Hope that helps,
