How could I fake this ornament in Dorico?
Thanks very much,
Maybe with a new Notehead that includes the line?
The symbol is in “other baroque ornaments” in Smufl. https://www.smufl.org/version/latest/range/otherBaroqueOrnaments/ (except it is named “… before the note”)
You can add it as text, or make a playing technique. This was resized to 20pt, with the default staff size.
Thanks so much, Rob!
