Chord tremoli within a larger beamed figure?

[Trevor Bača]

Hi,

Is it possible to get a chord tremolo of the type given in
chord-tremolo.ly beamed *within* a larger beamed figure?

Here's a valid chord tremolo; note that the tremolo marks do not touch stems:

%%% VALID CHORD TREMOLO %%%

\version "2.9.11"

\context Staff  \relative c' {
 \repeat "tremolo"  2 { c32 e32 }
}

%%% END %%%


And here I'd like to have that chord tremolo embedded inside the group
of 4 beamed eighths:

%%% FAILED CHORD TREMOLO INSIDE BEAM GROUP %%%

\version "2.9.11"

\context Staff  \relative c' {
  b8[
 \repeat "tremolo"  2 { c32 e32 }
  f8]
}

%%% END %%%

In this second example (attached) the tremolo marks unfortunately *do*
touch stems (which is rhythmically incorrect by half). Also here  the
interpreter grumbles ...

Parsing...
Interpreting music...
programming error: Stem already has beam
continuing, cross fingers
programming error: Stem already has beam
continuing, cross fingers
Preprocessing graphical objects...

... which probably means that chord tremoli within a larger beamed
group are specifically disallowed at present, yes?

Does anyone have a good way of embedding chord tremoli within a larger
beam? Is this a sponsorship opportunity?
