Suggestion to add edit button to catalog edits.

Quite a few times I've accidentally left something out or selected the wrong option while editing pages in the catalog. Each time I've had to cancel the edit and make a new one once I see the issue. I propose that there should be an edit button or w/e when you view the edit, and you can edit your catalog modifications while they are still pending.
