Swing for ternary music

Hello,

I'm experiencing a major issue with Musescore's playback of ternary music. Almost every traditional ternary music is interpreted with swing, and it only works for binary in the swing settings.

For example, in African music, or Maloya, the 2nd and 3rd eighth notes of every beat are player a little bit sooner or a little bit later than a regular mathematical interpretation. Common time-signatures are 6/8, 12/8, 9/8 and 18/8.

Would it be possible to add this feature ?

Attached is an image from my website explaining the different swings.

Thanks !
