Tremolo in notation but not in playback

Hi, first post in several years.

I have lots of observations about Dorico since getting into it in the last few months but one things that’s bothering me right now is that I have a string part with tremolo notation which plays back natural. Of course, I can’t change the playing technique in Play mode, which is irritating, so how can I fix this?
