We'd like the ability to add an Adobe esignature in the browser preview screen or the ability for approvers to upload via the Approval screen. 

Use Case: Following a submitted contract ticket, the details are sent to various signatories. These individuals review the contract details, contained within the ticket, and then esign a PDF document. We're trying to remove some of these manual steps and would prefer to have the ability to add an esignature via the browser preview window or the ability for Approvers to upload a document via the Approval screen.
