Is there a way to use the mouse wheel located on the throttle of Saitek X65F to zoom in and out while inside the cockpit for DCS A10C?

I have attempted to use the programming through DCS but no luck. The only time the mouse wheel works for zoom is when I believe it's F5 or F6 is used to go external view of the plane.

I am not using the SST software for a profile. I have no .pro loaded while I'm flying. I am only using what is programmed in DCS.
