Additional mouse sensitivity settings for zoom levels

currently i am finding it very frustrating to adjust my sensitivity for the wide range of scenarios you find yourself in.. if i set my sensitivity too low my short game is amazing...but for sniping and any sensitivity 3 and up i have to drag my mouse across my entire desk...which i would like to avoid as its a very small desk. if its too high my sniping game rocks...buuut i get screwed close game with fish out of water aim.

of course ive found myself in a crappy middle ground sensitivity currently,  however i cant help but wish there were settings in which i could set the sensitivity for each zoom level or. get rid of whatever is slowing down my aim at 3+ zoom level and unify them to  a general ads sensitivity setting. 

i've scoured the settings however i cant seem to find  anything remotely resembling what i need. ive honestly thought about making a sensitivity changing hotkey to swap back and forth from high and low sensitivities. but i want something ingame

let me know if i missed a setting somewhere. or if you too would like such a setting
