I have a tool where we manage projects on a hierarchical basis.
for Ex . 
At the top level there will be a main template with generic screens , fields , workflows. New projects can be derived from it there can be two possibilities 1. Everything same as template 2. there might be few changes to screens , or new fields might get added or might me some changes in the workflow. Same thing can be for project A and B. Is it possible to implement this structure in jira?
