Edit Email Campaign Title after it has been sent

This is a small nice-to-have that would be a “quality of [usage]” improvement IMO. 

Current: After you send an email campaign in CC, you cannot change the title of the email 

Desired: Ability to edit the email title after an email has sent

Use cases

• When you copy an email, make a small modification and hit send too quickly without editing the title
  • This happens to me semi-regularly, as I have a weekly newsletter I send with different audiences receiving slightly different versions. I’d love to be able to correctly label them instead of having [same title] (Copy) in my email metrics, etc. 
• When you iterate on a strategy for automated emails, turning one off and adding a new one
  • I may want to label the old one as “Archive” or “v1” or something like that
