1. Create two new projects with names starting with parentheses (e.g. "(Template) Project A" and "(Template) Project B").
2. Set both of these as template workflow steps for the same workflow (e.g. "Test Workflow") and have the second job triggered by a successful build of the first job.
3. Create a new workflow template project (e.g. "Test Workflow").
4. Create a new workflow from this new project.

The instances of the two projects will be created with the given names, but they will be related to the template jobs. I.e. "Project A Instance" will trigger a build of "(Template) Project B" on successful build.

(Put this as a "minor" priority as it's easily worked around by omitting parentheses from the job names.)
