I understood your question. The release mangèrent also indicated dtap is a very problematic topic.
The developing of code you make is possible that way but it is not commonly accepted by SAS institute.
Whatever you do with a tool it is about the goal the dtap segregation as with scrum itil being in the working set. It is bad not what you wanted to hear.
You would have liked an answer like use svn (possible with Sas di) or Jenkins or git. Sorry it is not that way.
