Merge two pitches of different

[Volodymyr Prokopyuk]

Hi,

The the following snippet

How can the last pitch A from both voices be merged? I understand that durations of the two pitches are different, so the default pitch merging does not happen. How can I achieve the desired duration of the pitch A in the first voice? I want to achieve the following

\version "2.25.18"

\relative {
  \clef treble
  \key g \major
  \time 2/4
  <<
    \new Voice = voiceOne \relative {
      \voiceOne
      \mergeDifferentlyDottedOn
      b''8. a16
    }
    \new Voice = voiceTwo \relative {
      \voiceTwo
      \tuplet 3/2 { b''16 fis d } \tuplet 3/2 { b d a' }
    }
  >>
}

Thank you very much,

Vlad
