Bank with mouse X-Axis

Hi guys!
Is there a way meanwhile to configure the mouse axis? I cant find a way and its really depressing
I want to Bank with the X-Axis of my mouse and Yaw with keyboard. I'm really used to this and dont wanna get used to the current settings which is Yaw with mouse X-Axis. It really kinda prevents me from playing right now since im so used to that
Hope there is a way! thanks guys...
