We have found that we will want to test out different templates, but cannot change the template once we have created an email. The biggest time that we run into this is we have our company logo template in English and French. If I want to clone an English email to simply add the French text, I cannot do this because I can't change easily from one template to another. It adds extra steps and causes me to have to have the English version open at the same time to make sure the formatting is the same. I want to have a button so that I can easily change the template once I have started working on an email.
