Inheritance of project configurations

We'd like to have some tool allowing the following for all project configuration entities - workflows, workflow schemes, screens, screen schemes, issue type screen schemes, etc. Workflows is just an example.

If we have, for example, three workflows: Workflow A, Workflow A1 and Workflow A2 and workflows A1 and A2 are a little modified versions of the Workflow A. Can we establish some relationship defining that Workflow A1 is a "child" of Workflow A? And when we modify Workflow A, then all its child workflows (A1 and A2 in this example) modifies automatically getting the same changes.

Can we expect that something allowing to do this will be appeared in JIRA?
