How to change Alt+Drag and Shift+Drag shortcut in Unreal Engine?

As a 3DS Max user, the ALT/SHIFT commands are reversed in Unreal, and for the life of me, I cannot easily switch between these differences. I always try to copy an asset by Shift+Click+Dragging it, and end up panning with it instead. The alt key is supposed to deselect, and instead it duplicates in Unreal.

I’ve looked everywhere in the General – Keyboard Shortcut settings and don’t see those keybinds.
