Email program a/b test - which version is which?

I'm using the new email program to send an A/B test, testing two separate emails. The test went out at 7am and so far it shows version B is performing much better, which is great... except I can't tell which one is version A and which is version B. The original dashboard screen where I set up the emails/test is replaced with a reporting dashboard. Does anyone know of a way to go back and check which version I assigned to A and B?

Thanks!
