Double flat/sharp accidentals on trills

Hey there!
I don’t find the way to tell Dorico to show a double flat accidental attached to the trill. The three interval positions you can change in the properties panel (1–flat, 2–natural, 3–sharp) don’t seem to include double accidentals. Aren’t they implemented yet?

Thanks!
Albert.

No, as yet they are not implemented, I’m afraid. There is more work for us to do on trills, including making Dorico choose the correct accidental automatically, and have that affect the subsequent notation beyond the trill correctly.
