Allow us to bind gadgets separately per class like we can with vehicles please!

I want my medbag on 3 on my keyboard, but my repair tool on 4, my tugs on 3, and my adrenaline injector on 5 or a letter. This is currently impossible to achieve, because these bindings are all linked. This poses an issue as I have 15 years of muscle memory of medbag on 3, rocket launcher on 3, C4 on 4, etc. 

I am completely unable to recreate the keybinds I've been using for 15+ years. Please let us have a "Support Gadget Keybind Override" "Assault Gadget Keybind Override" etc. option in the menu, similar to how each vehicle type gets its own section.
