Allow users to collect pdf doc in WordPress + download all pdfs at end

Hi there,

Is there an option for users to drop pdf files in to a “digital suitcase” and then download them all at the end with a “download all picked files” button?

Or something similar?

We have 40 pages and we want users to be able to go through different pages and store pdfs for a “download later” functionality.

Would be keep to hear your thoughts/advice
