How to edit an InputManager Axis' values through scripting?

This question should be pretty simple, so here goes. In the InputManager (Edit->Project Settings->Input) I have two axes called CursorHorizontal and CursorVertical. Basically when a certain condition is met in this script, I want it to change the sensitivity value of both of these axes. In runtime. Through scripting. I’ve looked at the documentation and I can’t find anything to change axes’ values during runtime… Any ideas how I can do this? Thanks in advance for any help.

There’s no direct API for that.
