You cannot currently edit the default email. It's not terrible, but not good either. I want to make a few small edits to the default, instead of creating an entirely new email. The default has a couple formatted things that I can't find an easy way to recreate in a blank email.
I don't want to change the default permanently, I'd like to save my edited default as a custom email, but I just don't want to be forced to start from scratch, just to change 10 words in an otherwise acceptable email.
