Allow printing or exporting of entire document collection

This is somewhat of a bizarre request, but here goes: I work in a corporate environment that has a requirement where some departments must keep physical (paper) copies of their documentation for business-continuity purposes (e.g., if the world erupts in flames and we have no computers, we need physical copies of procedures). Outline users can currently print documents one-by-one from Outline, but ideally, they'd like to be able to print whole collections at a time. That way, every 6 months, they can just go to their 5 collections and print the entire collection; this would allow them to click "Print" 5 times rather than 200 times.

Another way would be to have a "Download" option for an entire collection. That way, the user could export the entire collection to a single PDF and print that PDF.
