Changing camera zoom bindings

So I'm an ADC main who's been using MMB to Player-Attack Move for over 3 years and I've never had any issues with the camera until I got a new mouse that has a more sensitive scroll wheel. I tried looking for the key bindings for the zoom function only to find out that there's no way to do it unless you go and mess with the game files. How about making the zoom bindings changeable or at least change them to Page Up/Page Down as a default binding? I'm pretty sure there wouldn't be a lot of objections since zooming in and out doesn't affect the gameplay itself, unless you change your bindings like a lot of people do, and players don't usually tend to scroll in and out while they play. It's usually used either to point out a funny glitch/animation or to mess with it while watching replays, so even changing it to another keybind shouldn't be an issue.

Just some food for thought.
