Linear input curve: Controller

Are we able to get a small adjustment to the linear input curve?  It's my preferred curve, but I'm having issues with making tiny micro adjustments because the first bit of input on the stick makes my aim move too far.  I've tried adjusting zoom sensitivity lower, but that makes it too low to be practical, and raising deadzones isn't an option either. 

Could we just get a slight ramp at the start of stick movement so we can make those adjustments? I'm thinking like the first 1-2% of the input could be slower and the rest on a regular 45 degree trajectory.
