Multiple Doc packages saved separately with Certificate of Completion appended to each document

We are now required to save each signed document separately that is sent for signatures in a multiple document package. Each saved document must have the Certificate of Completion appended to the end of the esigned document.

Is this something that is available or coming so we aren’t spending time and potentially breaking the audit trail by saving separately and manually merging the document and CoC? These are for government transactions.

Thank you.
