Hi Patrick,

maybe this will get you started:

\version "2.19.15"

\new FretBoards {

  \override FretBoard.before-line-breaking =
  #(lambda (grob)
     ;(display (ly:grob-property grob 'dot-placement-list))
     (ly:grob-set-property! grob 'dot-placement-list
        (cons '(barre 6 1 1) (ly:grob-property grob 'dot-placement-list))))

  <f,-1 c-3 f-4 a-2 c'-1 f'-1>
}

HTH,
  Harm
