AssureSign final email notification Attachment Name

At present, the “Final.pdf” is used as name for the attachment in the final email notification sent by assuresign. However, this name differs from the one presented to users when they download the file via the “view envelope” in the final email notification despite both files being identical.

We would like to find a feasible way to synchronize the PDF name in the email attachment with the one downloaded through "View Envelope"
