\mark vertical alignment with Chord symbols.

[Jesús Guillermo Andrade]

Dear Fellows: I'm currently experiencing a problem with aligning a DC al fine mark, as show in the enclosed picture. How can I put it below the chord symbol? This is the setup for the \mark

melody = \relative c' {

  \override Score.RehearsalMark #'break-visibility = #begin-of-line-invisible

  \override Score.RehearsalMark #'font-size = #-2

  \override MultiMeasureRestText #'self-alignment-X = #DOWN

  \time 3/4

  \clef treble

  \key a \major 

  r4 e8 fis\( \times 2/3 {fis\)gis a} %1

.. ...

 gis8 fis e fis gis cis         %39

  a2.                            %40

  \bar "|."

  \override Score.RehearsalMark #'self-alignment-X = #RIGHT

  \override Score.RehearsalMark #'padding = #6.0

  \once \override Score.RehearsalMark #'outside-staff-priority = #-1

  \mark "D.C. al Fine" 

I just can't see how to put it between the staff and the chord. Any help will be appreciated.

Thanks

Guillermo
