How to Digitally Sign a PDF Once and Auto-Populate Remaining Signature Fields in Same Document

For PDFs that require a user to digitally sign multiple times in the same document, is there a way for the user to sign once and then auto-populate the remaining signature fields?

A digital signature applies to the whole document. It doesn't make any sense to have multiple signatures (by the same person) in the same file, nor is it possible to automatically do it.

Thank you for your quick response.  I agree with you that the purpose of the digital signature is for the entire document...this is an inherited document that contains a combination of contract requirements containing "approval" signatures in multiple sections.

People often don't understand that what makes sense for "physical" signatures doesn't work for digital ones... You can try and educate them on the matter, but it's often a lost cause.

Anyway, the user will have to sign each section separately if you want to do it like that. Keep in mind that with each signature the file-size might double, as a copy of it is being saved for future reference. So if you have 5 signatures on a 5MB file it can be 25MB (or more, since each copy contains a copy of the previous copies) by the time you're done with it...

Didn't realize the file size increased so dramatically with each signature...thank you...that point will help build a future case for one digital signature for the whole document.
