It may not help, but my work flow does a folder where all these da pages exist. Then I create an index.php in that folder. I load that first, then do all the insert, results, etc. I've always done it this way but my clients have password protected for their admin.
Then, I create a template for that index.php page. Then I apply the template to all the new DA pages. (Previously, I did the template first and applied during da, but the system has changed.)
Hope this helps someone.
