Adobe Sign API - Attaching Recipients to the Document

Hello, I am trying to create an application that uses the Adobe SIgn API to send out a document to signatories. 
My question is as follows, Is there a way where I can handle the following use-case:
- Attach a document to an agreement.
- Create the agreement along with the recipients and save it as a draft.
- Redirect the user to an interface where he/she can view the uploaded document and specify where each signer can sign on the document.
- Once complete the user can send out the agreement to all the recipients.
- As the document is being signed by each signatory, I can view the process through the API and download the completed document once the cycle is complete.

Thank you for your assistance.
