Possible to pull reports that span multiple teams/projects? Edited

[Leo Kelly]

I am trying to see if there is a way to pull agile metrics for multiple teams/projects at the same time - for example, pulling metrics/reports for, say, 10 different teams that are part of the same business line but are otherwise completely independent from each other. I know there's not a clear way to do this (at least not from what I can see) but I was wondering if there are any plug-ins or tips for how we can do this. 

To complicate it further, same of these teams are Kanban, some are Scrum. 

We will be moving to Jira Align next year, which I think should make this easier, I'm trying to work out some kind of a stopgap. Might not be possible but thought I'd ask!
