You can create a template that contains the recipients with the roles that appear on the auto tag matrix. You can move these recipients into the order that you want and save this template.
Upload the template that contains the signing order and then upload the document with the auto tags and apply auto tagging.
The recipients should be placed into the correct signing group as the template.
Upload a document, apply auto-tagging, and then create and move the recipients into the signing group as needed.
