Tameable Zombie Conflicting AI Checkboxes

So at the moment, I am trying to make an entity that is a zombie but follows you and acts like a wolf by attacking the mobs that you attack and that attack you. At the moment, however, I can't have it tameable if I use the "Enable AI" checkbox and by using the "Animal AI" checkbox which makes it tameable, it ignores the base entity of a wolf and instead just follows me.
