As a customer journey owner, I want to be able to easily see how well emails are performing against each other in a journey, so that I can make changes where appropriate.

Customer journeys with more than a handful of emails in it are exceptionally difficult to compare against each other as there is no list view of the email performance stats available.  In MDM, a list view could be configured to show all emails with stats, the campaign they were attached to, and also a program.    

With the current scenario, you have to go into each email to see what's happening and write down what's happening outside of the system.  With automations that are continually changing or journeys with more than a few emails, this is not practical.  This is a big gap in the product.
