Yes, with https://sourceforge.net/p/testlilyissues/issues/5156/

Did you try convert-ly from 2.21.0? Make sure your file has the
\version-statement according to LSR, i.e. 2.18.2
You would get:

\relative c'' {
  \once \override TupletNumber.text =
    #(tuplet-number::fraction-with-notes
      (ly:make-duration 2 1)
      (ly:make-duration 3 0))
  \tuplet 3/2  { c4. c4. c4. c4. }
}

But this works as well:

\relative c'' {
  \once \override TupletNumber.text =
    #(tuplet-number::fraction-with-notes #{ 4. #} #{ 8 #})
  \tuplet 3/2  { c4. c4. c4. c4. }
}

Cheers,
