Honestly, this was something that Fallout 4 and Fallout 76 could have benefited from. There were people who used Nuka-Cola for healing instead of stimpaks, especially with Fallout 76's Cola Nut perk, but one significant benefit of using stimpaks instead was that you had a binding for them when using a controller instead of a keyboard.

Console players don’t have hot keys so I’d like to be able to choose what’s on the right d-pad button Since it’s the only instant use button I have available. I’d actually prefer if you could bing any item to that button. It would make using the cola nut perk way easier.
