Tuplet Tremelo

I am trying to create tuplets to represent repeated triplet quavers. I have found a work-around by creating the tuplets then lengthening the first note duration to fill the whole tuplet and then adding the single bar tremelo. (See attachment with this in progress.) This plays back as straight quavers.
Is there a simpler way to do this, which also plays back correctly?

Please check

Unfortunately there’s no way to achieve the correct playback of measured tremolos on tuplets at the moment; this is something that needs more work on the playback side of the application.

However, you should find that it’s pretty simple to create the tuplet in the first place: type 6:4e into the tuplet popover, then fill the resulting tuplet with a dotted half note/dotted minim.

Thanks for the tip Daniel. Sorry I missed the other threads - I definately need to improve my search skills!
