printing rest in ChordNames context

[Zoltan Kota]

Hi,

Is it possible somehow to display rest symbols in a ChordNames context?

For example:

...
dalchords = \chordmode {
   c1 | bes4/d r f2 |
}

\score {
  <<
    \context ChordNames {
      \germanChords \dalachords }
    \context Voice = dala \dala
    \new Lyrics \lyricsto "dala" \dalaszoveg
    >>
}

And above the Staff I want:

C    Bes/d "r4_symbol" F
