It is true that if you copy/paste the FC Controller/FSM Owner component, the referenced blackboard remains the one that originally was referenced (this is typically how Unity works). However due to this reason, in recent NC/FC versions, the Blackboard is an exposed field on the FSController/FSMOwner component and as such you can for example assign any Blackboard Component you want. In your case for example, you can simply drag & drop the Blackboard that exists on the same gameobject into the “Blackboard” object field to link it.
