Artboard type workflow out to multi-page PDF?

This could fall under multiple scenarios. One example:

I import a multi-page PDF into model space, make some adjustments and/or notes on some/all of the pages, and then want to export the pages (using their original boundaries) right back to an updated multi-page PDF.

There are multiple ways to do it fairly quickly by hand – isolating a page’s geo and creating a new layout sheet would center that geo/page in the detail viewport. Wash and repeat for each page, then print the layouts to a multi-page PDF. Or even quicker if you don’t need to have layout sheets set for them is to just select what you want on a page, export as PDF (using the following setup) and then wash, rinse, repeat.

But is there a workflow already in place for this?

And if not, is there a script anyone has for something like this they’d be willing to share or tweak to fit the need? Maybe a “for” loop sending individual layers (each PDF page on its layer) to “fitted sheets” like in Peter’s Tools (though only the Top view zoomed to page size) could work? It’s a bit out of my league and I don’t have the time to brute-force it at the moment, or I’d try to tackle it myself. :sweat_smile:
