I am using alot of sub graphs for modularity and it would be great to have the ability to override the agent sub graph is using so i could re-use graphs that contain bound blackboard variables of other graph owners.
That could be an interesting addition. Do note however that this is already possible with an extra node (Decorators/Override Agent). You can add Override Agent decorator just above the SubGraph node and it will basically have the desired effect considering I understood correctly.
Is this the same as your suggestion, with difference of course being for this to be done within the SubGraph node without the need for the OverrideAgent decorator?
