If you absolutely must have this look:
!NoteWorthyComposerClip(2.74974,Single)
|Note|Dur:8th,Triplet=First|Pos:0|Opts:Stem=Up
|RestChord|Dur:8th,Triplet|Opts:Stem=Down,ArticulationsOnStem,HideRest|Dur2:4th|Pos2:2
|Note|Dur:8th,Triplet=End|Pos:-3z|Opts:Stem=Up,StemLength=0,Muted
!NoteWorthyComposerClip-End
Play back won't be quite right, though...
