For instance, let the druid in your party be the one to run around harvesting herbs, mushrooms etc.
That doesn't even require " a brain". just the basic UI mechanic already implemented in several games of this type to have the person in the party with the best skill/inclination for the task doing the action.
Pathfinder Kingmaker does it by default.
If you pick an herb/mushroom or loot an animal, the character with higher Nature goes first, if you pick a lock it's the one with the highest lockpicking skill, if you select an athletics check your most athletic character moves forward to do it, etc.
