Hunt deer by pressing the shift key

Suppose we have 4 deer near a mill, and we hunt them, then to avoid wasting food, I select 4 villagers and give them the order in which they have to hunt each deer, thus avoiding having to exert more control over them and forgetting, To the surprise, despite giving him a hunting order, there are times when, for example, 3 villagers go to a deer and another villager to another deer, he does not respect the order.
