Double Check Before Attacking Allies/Pets

[Ares]

Could there be a togglable setting (default set to on) to ask before going through on an attack on followers/pets (the same kind of yes/no when it asks if you want to enter water)? Obviously for some people they may wish to do this often enough to not be bothered with it asking every time, hence the toggle. However, I often accidentally mistarget a friend or pet in combat, which is very frustrating with a permadeath game.
