That's why they gave you the "Engage"/"Disengage" options.
The game actually tells you before hand if a group of enemies will aggro as a group. If you stop and look you will see lines that link grouped mobs together. There's no reason the NPCs shouldn't be able to distinguish between trash pull groups that need aoes and boss mechanics where the tank shouldn't be running around for every tonberry that will be dead before they reach it.
