Smooth zooming in viewport

Hi all,

I have experience with Maya and C4D and I’ve become very accustomed to the way viewport navigation works in them. I know that one can set the key-mapping to that of industry standard; however then the orthographic views’ key-maps on the numpad gets changed (which is a no no).

So I’ve set up different key-mapping for camera panning and rotating on the Blender key-maps BUT I want to add the function to smooth zoom via ALT and RIGHT CLICK and dragging the mouse up and/or down. I know that it is mapped to CTRL and MIDDLE MOUSE on the default Blender key-map.

I realize I can just go into the settings and do it manually but I’m afraid of effing it up too much. So I’m hoping that someone here might have already sorted this out (hopefully).
