Orbit on right mouse button

Hallo

I want to reproduce the right click behavior I have in rhino where for orbiting models I click and hold the right mouse button instead of the mid mouse button

I also tried by inserting the orbit command to the mouse customizatin panel in bricscad but i end up with a click behavior, not a click and hold behavior like the mid mouse standard behavior.

Is there a specific command I need to use ?
What is the command used in the mid button orbit to make it on click and hold ?

Thanks

Luca
