Placing (some) outside-staff objects horizontally rather than vertically

[Joel C. Salomon]

The attached example has simultaneously a text mark, tempo mark, and 
section label.

Is there a way to get Lilypond to place them next to each other 
horizontally, rather than stacking them vertically, to match the 
original score?  Ideally, this would obey `outside-staff-priority`.

(Yes, there is: by manually tweaking the anchors for the various marks, 
till they end up approximately where I want them; see below.  I'm hoping 
there's a cleaner option available.)

music = \fixed c' {

dynamics = {
  \set Score.tempoHideNote = ##t
  <>\tempo 4 = 80
  \after 4*3 \tempo "Tempo Mark"
  \skip \music
}

up = {
  \after 1*2 \sectionLabel "Section Label"
  \music
}

\score {

    \up
    \new Dynamics \dynamics

}
