Separate a tuplet from the rest under a common beam

[Volodymyr Prokopyuk]

Hello,

Problem

How can I separate a \tuplet from two sixteenths using a common eightingth beam?

Example code

\version "2.23.81"

\relative {
  \clef treble
  \key c \minor
  \time 2/4
  \tuplet 3/2 { g'='16[( aes g) } fis g] a8 b |
}

Desired result

I've tried to adjust the baseMoment, beatStructure, subdivideBeats and strictBeatBeaming but without success.

Thank you very much,

Vlad
