I am absolutely outraged by your recent automation setup changes. You should DEFINITELY be able to duplicate an entire auto series. Business create more than one automation series for different reasons and like to lift previous email templates and formats without having to recreate. Worst case, you should DEFINITELY be able to duplicate emails from a previous auto series not limited to only the most recent campaigns. I have auto series set up from months ago and I'm always creating new auto series. I should be able to go back through all of my previous campaigns to duplicate emails like I used to be able to.
