Trying to Combine Signed PDFs, Signatures are being Deleted

[Lou31445610p0e2]

I'm attempting to merge multiple documents into one single file to send out to the required entities. All the files are digitally signed when opened individually, but when I try to combine them, all of the signatures disappear.

Is there a way to keep the digital signatures when editing other parts (dates/misspells/etc.) and/or combining multiple signed documents?
If not, is there a workaround?

Combine the files as a portfolio.

No, and this is by design. A digital signature is meant to ensure the file is not edited once signed. Merging it with other files is also a sort of editing, so it will either be stopped, or the signature will be removed when you do so.

As mentioned, you can combine the files as a Portfolio, though, which is an empty "envelope" that holds other files (PDF or otherwise) as attachments.
