This was discussed recently here:

But, instead of OUHM, you could perhaps do it like the "Expressive marks" 
snippet "Center text below hairpin dynamics" (cf LSR 223) 


midHB =
#(define-music-function (parser location text) (markup?)
#{
 \once \override Staff.HorizontalBracket #'stencil = #(lambda (grob)
   (ly:stencil-aligned-to
    (ly:stencil-combine-at-edge
     (ly:stencil-aligned-to (ly:horizontal-bracket::print grob) X CENTER)
     Y (ly:grob-property grob 'direction)
     (ly:stencil-aligned-to (grob-interpret-markup grob $text)
     X CENTER) 1 0 )
    X LEFT))
#})


\midHB \markup { X } a'\startGroup b'\stopGroup
