Zoom FOV Options

[Crunch_]

Hello,
There is the option to map a key to different FOV levels, insert, delete, etc.

You can also click the middle mouse button, then hold down the right mouse button while moving the mouse along the Y-Axis to zoom the FOV smoothly.

Is there a way to map zooming the FOV on a key or joystick button smoothly like the mouse option?

Thanks
