No.  If it is Chopin, what Opus and Number is it ?

If possible, use a more standard way to show whatever this means.

You can set the number of beams fairly easily, but LilyPond always
draws the outer beams so the span across the inner beams

\relative c''{
\set subdivideBeams = ##t
\once\override Beam #'beam-segments = #
(lambda (g) 
  (let ((segs (ly:beam::calc-beam-segments g)))
    (display segs)(newline)
    segs))
c16[ d e f d 
\set #'stemRightBeamCount = #0
e
\set #'stemLeftBeamCount = #0
f g e f g a] r4 }

You could probably add some Scheme code to pick out the middle beams
with "vertical-count 1" and replace them with a single beam.
