Did anyone figure out how to use inverted mouse?

Hi All!
Myself, and my children all use inverted mouse controls. My kids are fascinated with virtual construction and it’s a shame we can’t use the editor without frustration. Why would such a standard option in in FPS games [invert mouse] be overlooked? We inverted mouse users exist! I know we’re just the specs but I see options to ‘invert’ which SAVE but have no effect on the backwards controls I am suffering through trying to use your editor. If anyone can share how to use inverted mouse function in the editor that would be awfully nice.
