Tremolos with stroke dots above

Here’s something I’ve not seen before. I’m doing a transposition of a trumpet part and cannot find a way to render these vln cue tremolos with the dots above. Not needed for the trumpet, of course. Dorico’s way of doing cues is marvelous.

Create a custom playing technique for it and set cues to show PT.
