Combine and selectively export PDFs in Innovator

Hello!

I'm looking for something to add into Innovator that would allow my users to take multiple documents with attached PDFs and be able to selectively output them as a single PDF. For example, I could have 3 3-page PDFs. I want page 1 from PDF 1, page 2 from PDF 2, and page 3 from PDF 3 but not their other pages to be exported a single, new PDF (only 3 pages, not 9).

Are there any tools or converters you're aware of which are compatible with Innovator? Preferably something that can be embedded into the Aras installation as our clients use secured, on-prem versions and thus can't make calls out to other websites.

Thanks in advance for your help.
