Hello and sorry for the very late reply (I was ill).
While there is no ability to save the Blackboard as an asset right now (looking into this), there is a nifty toolbar command to automatically create blackboard variables of all “Defined Parameters” in the graph.
This is (in the NC Graph Editor window), under “Edit -> Promote Defined Parameters To Variables”.
This will search your graph for defined parameters and fill in the blackboard with required variables of that name and type.
