How do I create an Adobe Sign Agreement List Button in Salesforce?

Hello! I've started working with the Salesforce Adobe Sign app, and it's going relatively smoothly - I have a template set up with a document and merge fields, but we have several types of agreements (related to Opportunities) we need to send. I can create buttons on the Opportunity detail page, but would like to have the buttons appear in the Agreements Related List portion of the Opportunity detail - is this possible?
