Pointer to scroll feature

I'm using a logitech trackman marble and all software for getting the ball to act as scroll out there are really bad... I have it set up now so that it scrolls when i have one button pressed.
Would love this as a feature in BTT!!

Is there a way to do this with BTT. Cursor-move to scroll, while pressing a button.

How did you achieve this functionality? I have been trying to figure out how to do this with my trackman marble on my 2015 MacBook Pro (10.14) but have continued to come up short. If you could post your solution I would be eternally grateful.
