Completion_heads_engraver

[Stefan Kägi]

Hello

I have a question about the Completion_heads_engraver. I would like it
to use it in such a way that it splits the bars in halves, then
quarters and so on.

This is my code:

\new Voice \with {
  \remove Note_heads_engraver
  \consists Completion_heads_engraver
  \remove Rest_engraver
  \consists Completion_rest_engraver
}
\relative {
  
  \set completionUnit = #(ly:make-moment 1 4)
  
  \repeat unfold 10 {
  c'16*23
  }
}

In this case I would prefer if in bars 8 and 11 there wouldn't be a
half note in the middle but rather in the end of the bars.
Is there a way to do this?

Thanks!
Stefan
