Device Panel for virtual instruments?

Is it possible to create a user Device Panel for say, the Mod Wheel on HALion?

There are times when I’m only using my laptop and a MIDI Guitar, that I’d like one or two on-screen sliders for CC#1 and maybe 11.

I understand the concept of how to create the panels, but just not sure how to go about it with virtual instruments.

Thanks.

Silly me!
