Contract Edit and Sign Workflow

We have been using Adobe Sign for many of our business workflows. We are hung up our teaming agreements and NDA contracts that we send to other businesses. Right now when changes are needed, a workflow has to be cancelled or declined and the process starts over once we've made the document edits. We're looking for more capabilities within Adobe Sign to avoid this disruption in the process - highlight tool, comment boxes, etc. for the contract receipient to adjust the document before approval and signing.
