I would like the ability to choose what is considered an upgrade for my troops. Often the game chooses things like legendary armor above magical, or masterwork bows over yew bows. I realize that I can simply choose the weapons I want when I create a unit, but if I have a group I made before I learned to craft magical weapons, I would like to be able to upgrade their weapons as I choose, not simple what the game thinks I want.

I don’t mean individually managing every little group. More along the lines of a customizable upgrade window, similar to the unit creation window. It would default to the best equipment available, but you could go back and choose something like the boreal sword as the weapon the at all edged single handed weapons would upgrade to.
