Zoom in Zoom out option

Can we get a zoom in zoom out option in our game pad configuration? I think it would be cool to have that durning regular game play cause i like to zoom some what all the way out in 3rd party view when im fighting, then zoom in halfway close when im idle to enjoy the game scenery, also it would be cool to have it on the map to zoom in and out of the map layout. i play with the wireless xbox gamepad and would be nice to have the trigger button dual operation to my macro in battle and then zoom out in passive mode.
