Quick zoom but not holding it

[McPetterson]

I was wondering if an option exist for usign quick zoom, but we don't have to hold the mapped key, only press the button and have quick zoom max or min by pressing it one time ?

I wasn't able to find an option to map a joystick button to "Quick Zoom: Maximum" without the view snapping back to normal when releasing the button, so instead I've mapped one button to "Pilot head: Zoom In" and another to "Pilot head: Zoom out", allowing me to quickly zoom in by repeatedly pressing that assigned button for firing and then back out to regain my situational awareness.
