Hairpin whiteout problem

[Ben]

Hello!

Is it possible to whiteout hairpins? I can't figure it out.

Code example:

%%%%%%%%%%%%%

\relative c'
{
  c2 d e\< f g_"C" f\! e d c
}

%%%%%%%%%%%%%

I'd like for the "C" in this example to be inside / on top of the hairpin. Is there a way to have *any* type of object whiteout a hairpin, whether it's a multiphonics diagram, or markup, or anything?

I've tried other solutions from the mailing list but they don't work here.

\override Hairpin.whiteout = ##t
\override Hairpin.layer = #2
\override TextScript.staff-padding
etc.

(please see attached)

Thanks so much!
