How do I add my signature to a document prior for others to sign

Typically I just set myself as the first in the workflow. Example, you require 3 Signatures from 3 Recipients, you and 2 others. Create the envelope, add document, set order as Recipient 1 (You), Recipient 2, then Recipient 3 all set to Needs to Sign. Add tags, placing signature tags where appropriate based on color coded Recipient dropdown. Send. Because you have a DocuSign Account you should get an automatic popup asking if you want to Sign. Select Ok or Yes....sign, then the envelope proceeds to further routing and Signatures.
