In Sitefinity 5.1, we relied heavily on shared content blocks to create both a page and an email campaign issue. We would create the page, create each block of the intended campaign as a shared content block, then we would create a new campaign issue and select each of the shared content blocks to ensure the issue was identical to the page.
Now, after upgrading from 5.1 to 6.3, shared content blocks are no longer available inside an email campaign issue. Also, Page Templates and Message Templates are different, so I can't create a template, and use it for both a page and an issue (from what I can see).
How can I now, in 6.3, create campaign issues identical to "view online" pages without resorting to clicking the HTML tab on each and every content block and doing a copy/paste?
Any insight would be appreciated!
