Is there a way to aggregate reporting on Advanced Outreaches?

I have several versions of the same AO due to having to make minor changes to its flow. I'd like to be able to gather the metrics for the emails in a single report rather than having to go into each AO separately - is this possible? 

How are other folks aggregating email reporting across the several AOs? My goal is to have an easily exportable report that can be shared externally consistently.
