Use 2 "Natural" in expression map?

Is it possible to have 2 “Natural” expressions, one controlling the “Volume dynamic” with Note Velocity and the other controlling “Volume dynamic” with Control change?
I ask because the plugin I’m controlling (Guerrini Converter Accordion), is responding to key velocity and to Control change 1 and I would like to use both for maximal expression in the dynamics.
I have tried but with no luck.

It’s not currently possible to do this, but it’s something that thinking about for future versions. In the meantime though you can use now velocity and then draw in the cc1 values in Play mode

Thank you Paul!
