I'm not even sure that XIV will have the ability to do stuff like this, because of how the UI/hotkey/action bar thing is. Unless they add a new action bar that's only usable when you have a Primal present. I just don't see how they'll possibly do it without keeping the pet with an AI that it sticks to.
*Revelation*
Unless the Arcanist learns abilities which make Carby do certain things, like "Attack", "Debuff", "Heal", "Defend" etc. In which case, those abilities would still be accessible to SMN to let the Primals do their own move which is related to that command. E.g., using "Defend" with Ifrit would be a Sentinel effect, whereas "Defend" with Garuda could be Featherfoot.
I guess in kiiind or the same way that the Magus Sisters in X perform actions, but with less 'randomness'.
