Two HorizontalBracket over the same note

[Jose Carlos Alvarez Gonzalez]

 Hello to everyone,:)

I'm José Carlos and I'm newbie on lilypond and I can not be able to do the
following idea:
I want to add two HorizontalBracket over the same note (one of ending and
one for starting, to put the numbers of tones or semitones that the
interval have)
https://paste.debian.net/plainh/c955f325

\version "2.22.2"\relative c' {
  \omit Staff.TimeSignature
  \cadenzaOn
  \override NoteHead.style = #'default
  \override HorizontalBracket.direction = #DOWN
  \override HorizontalBracket.connect-to-neighbor = #(#f #f)
  \once\override HorizontalBracketText.text = "1"
  d1 \startGroup
  e\stopGroup\startGroup \once\override HorizontalBracketText.text =
"1/2"
  f \stopGroup}\layout {
  \context {
    \Voice
    \consists Horizontal_bracket_engraver
  }
}


The problem is that HorizontalBracket  is grouping the two interval. In
that example, i want to see:
d (1) e (1/2) f

I have to try to overried HorizontalBracket.connect-to-neighbor:
\override HorizontalBracket.connect-to-neighbor = #(#f #f)

but that not works for me.

Thank you very much for all

:)
