Exporting all pages/assets in order to make a CMS Collection

We made a mistake early on in creating individual Learn More pages for our customers, which spiraled until we now have something like 80 pages. It’s an obvious case for a Collection and template.

That said, being that many of these pages have background images and other assets that we need to drop into a Collection, is there a way to export all of the site pages en masse into a CSV (like we would a collection), or any other way to make this process easier?

You can export the site and when you unzip the site zip there is an assets folder with files that were uploaded.
