Give me a PC game built for PCs which doesn't cater to console gamers and shoddy ported menu systems that are obtrusive when using a keyboard and mouse.
Could they add this feature in now? Sure, but I'd be rather annoyed if they were to do so when the UI could use some improvements before thinking about controller support. Even after some added polish to the current UI and bug fixes I'd rather they worked on good old fashioned expansions, not modern day micro DLC, to part more of my cash from me.
