No MiniMap Zoom Keybinds

I notice that there is no way to change the keybinds that zoom in/out the minimap. It seems to be set to numpad + and -, which I unfortunately use for other things on my PC. This is not listed in the inputs, so I can't change it to something else.

Is there a place I can request this as a feature: being able to remap the keybands for zooming the minimap?
