Unreal doesn’t have any shortcut functionality at all, or music streaming which is why we use FMOD to handle Soundcloud streams. We’d have to implement it ourselves on each system.
I’d be honest, this type of feature will most likely not happen for a long time, if ever. Not because it’s a terrible idea, but because it’s so low on the priority list that it’ll most likely be forgotten. I personally love the idea, though.
