How to change the button for panning in orthographic view (top, right,etc) to middle mouse button ?

I want to change the shortcut for panning from RMB to MMB. I found this option for blueprint editor but I was not able to find it for level editor in orthographic view.

Also, please let me know if there is a way to use middle mouse for panning in all editor window. I am new to unreal engine and I am still unaware of other editor windows which use RMB for panning.
