I was wondering it might be possible to create an option where you had the ability to copy sections from one email campaign to another campaign without having to recreate it.
Thanks for reaching out to the Community about your email! I can understand how helpful it would be to save content and be able to reuse in other email campaigns in your account. I apologize this is not a feature that is currently available. The good news is this is a feature request our Product Team is currently collecting feedback on. So we have tracked this feature request in your account and submitted it to the appropriate teams. Instead you will have to manually recreate the block, or copy the email that the block is in and delete/update the other blocks.
