As in, allowing you to tell a follower to favorite and use specific items, and that sort of thing? Or am I just remembering incorrectly, and that was just Gamejam stuff?

Well i do remember reading a post somewhere on the forums mentioning it would be a good idea. but i do not believe that they have, sorry. : /

Eh. That svcks. Oh well. To the Nexusmobile, Robin!

There is lot of mods out there that can do that but not in vanilla game

Yup. Mods it is then.

Check out UFO, the best IMO. Couple that with specialized followers, though it has to be lower in the load order.
