How do I add/edit the transaction address in Real Signature? For example, I created a transaction before I knew the address.

You cannot add/edit the transaction address in Real Signature at this time. You need to first create the transaction in reZEN, then it will be available in Real Signature to associate your Forms / Files to your reZEN transactions.

If you already sent the document with Real Signature, you can download the document in Real Signature and upload to your File Cabinet / Checklist in reZEN. See: Step 2: Upload Transaction Documents
