chordmode markup problem

[Bernhard Ott]

Dear all,
is there really no way to simply add articulations/markups to chords in 
\chordmode?

In 2.14.2
\chordmode { c1\pp } works
\chordmode { c1^"II" } doesn't (as mentioned in the docs).

Could scheme do the trick?
I need the chordmode for *quick* engraving of basso continuo music, so I 
would like to avoid messing around with extra voices "just" for 
indicating keyboard-changes or stops.

Thanks in advance,
Bernhard
