@matthew_mcgrath have you seen anything like this in your work with AdobeSign and Salesforce?

Hi @jredwine,

I heard you spoke to @Brent_Doc and got your issue resolved. Please mark as resovled if the below solution provided is correct.

Solution: Create an insert update on the Document Package that passes the Custom Object's record to the AdobeSign "Agreement" object. 

That documentation can be found here - https://community.nintex.com/t5/How-To-s/Drawloop-Adobe-Sign-Echosign-How-to-attach-signed-document-to-a/ta-p/100196
