From reading the documentation/advertising material, if the app (i.e. Dorico) was aware of the Dial, then Dorico could reprogram the Dial short cuts on the fly (for example, change the labels, and make them context-sensitive).
But since the current version of Dorico isn’t Dial-aware, the Dial can only generate a fixed set of keystrokes, which you can customize using the app that comes with the Dial itself. Dorico doesn’t “know” whether you did something using the Dial, or just pressed a key on your computer keyboard.
