Removing the accidental in a pitched trill?

[Trevor Bača]

Hi,

Pitched trills seem always by default to print an accidental:

 \pitchedTrill c'4 \startTrillSpan d' c'4 \stopTrillSpan

Is it possible to remove the natural sign from in front of the D?

(There is TrillPitchHead grob which the docs list as implementing the
pitched-trill-interface. Looking up the pitched-trill-interface, I see
the lone property of accidental-grob, which is listed as internal. Is
it somehow possible to user set this property to nothing to remove the
natural sign?)
