Slurs, phrasing slurs and fingering

[Olivier Biot]

Hi all,

Is there a simple way to avoid fingerings from being overwritten with a phrasing slur, like in the following measure?

% BEGIN
\version "2.16.1"

theMusic = \new Staff {
  \relative d' {

    \key f \major
    \time 3/4
    \clef "bass"
    \acciaccatura { e-\! } d4  cis8-\> \( ( a'16-.-3 ) a-.-\! \)
  }
}

\score {
  \theMusic

  \layout {
    \context {

      \Staff
      \override Fingering #'add-stem-support = ##t
      \override Fingering #'avoid-slur = #'outside
      \override TupletBracket #'bracket-visibility = ##t
    }
  }
}

% END

The following directive works for regular slurs:
      \override Fingering #'avoid-slur = #'outside
However, phrasing slurs seem to be immune to this ovverride...

Best regards,

Olivier
