\tuplet 2/3

[bobr...@centrum.is]

I need to print half-note duplets in 3/4 time.  '\tuplet 2/3' does not work.  
The code below *does* work.  My question is; is this the "right" way to do this?

Thanks,

David

\version "2.20.0"

\score {
  \relative c' {
    \time 3/4
    \once\override TupletNumber.text = \markup{ "2" }
    \tuplet 4/3 {c2 c}
  }
}
