Copy secure messages over as a thread

Copying to contacts: Instead of copying each email individually, possible to copy a string to the contact files. i.e., When I had to make a PDF of emails, I would wait until the whole conversation string was done, THEN make a PDF and put it in the contact files. And if not, as there a way Theranest can give us this option, so we don't keep putting individual emails into the contact file?
