(I did read the answer to this, but it seems specific to out of box templates, so I'm hoping for a different answer here.)
Is there any way to find a list of pages that were created with a custom global template? I recently took over as admin of a Confluence site that previously was completely open to everyone in the company, and we now have dozens of custom global templates, which really clutters up the Create dialog. I'd love to be able to get rid of them, but would like to be able to quickly audit how many pages have been created with each, where those pages live, and how recently they were created.
