I have a pdf document from supplier. After I have reviewed the document, I made some comments and submit to the supplier for his checking. The supplier comes back with comments with another pdf document.

So I actually have 2 pdf documents. The first document will have some comments made by me. The second document will have comments made by the supplier. Is there a way to combine these 2 pdf documents in EPDM, so that I can see the history of the 2 documents and track which are the latest versions?

Thanks in advance for the help!
