If comparing apples to apples like Flow from a previous year that was re-done in a new Flow - 

Where would you look at average metrics for events that occured across the Flow?

So, I can pull all kinds of data by month and by email within a flow, and continue to work it out on a spreadsheet.

But, #1 - Does this report exist? And if it doesn't… I can keep working my spreadsheet.

And, #2 - It would be helpful right? Metrics from the Flow as a unit? To see by Flow in addition to per month/email etc… If I have that data across a flow I feel like that can create a higher-level view comparison.
