How to create a e-sign without a certificate

Hi everyone,

We’re trying to determine the best way to handle a recurring multi‑signer PDF workflow without permanently locking the document.

Scenario:

• We send a PDF to multiple signers.
• At the end of the signing process, the PDF becomes locked due to a digital certificate.
• The same PDF needs to be used again at the end of each month for a callback process and must be signed again.
• Once a digital certificate is applied, the document cannot be modified unless it is printed/recreated, which breaks the workflow.

Additional issue:

• After monthly reports are called back, we combine all signed PDFs into a single PDF for compliance submission.
• When combining PDFs that contain certificates, the signatures are stripped from the final combined document upon saving.

Question: Is there a way to:

• Send a PDF to multiple signers without applying a document‑locking certificate, or
• Configure Adobe Sign/Acrobat so the document remains reusable and signatures are preserved when combining PDFs?

Any guidance, best practices, or recommended workflows would be greatly appreciated.

Thank you.
