Howdy!

Please, if there is an elegant way to perform this adjustment, do let me know.

I'm hanging (virtually) two projectors that will edge blend IRL.  Both will hang off the 2nd electric.  In Capture, I light up both with a test pattern to show the overlap (2 video players).  Ideally, I'd like to hover my cursor over the "Selected Item" parameter and roll my scroll wheel while I watch the result on the (virtual) screen.  Big scrolls = Big movement, Small scrolls = Small movement.

Can this be implemented?  Is there an elegant way to do this already without typing or dragging symbols?

Thanks for your consideration!
