A way to create an expression map for Cinematic Studio Series?

Has anyone created a reliable expression map for Cinematic Studio Series that fixes some of the hurdles when trying to switch to specific articulations? I’ve been looking for a guide to setting them up, the big issue is that you have to use more than one keyswitch to trigger a certain kind of articulation such as say legato and sustain. I found an article about how to get around this on Cubase but I’m unsure if it would also work for Dorico.

There was this thread not long ago, it could help?
