Hyperlinked pdf

Our schools are requesting a hyperlinked pdf of the textbook. Meaning I would take the pdf of the textbook currently on our RACHEL, add hyperlinks into the text to the relevant KA-lite, CK-12, Phet, etc. videos, and then upload that new pdf back onto the RACHEL. Wondering if this is possible or if anyone has done this? How would I hyperlink to the correct link that will work offline?
