"Level up all" button for hunting

I would be interested in a button that when clicked will level up all the hunters that are able to be leveled. It would be located in the "Hunting" section for convenience next to the edit button and the same size too (large enough to see but small enough to not be in the way).

Thatd be nice honestly, there's only 5 though so it wouldn't be too significant 

i support. 

i can see how this can be useful if you have several hunters that need to level up.
