Hi everyone,
I created a new Issue Type "Request" and would like to add this new type as a child-issue option in the Epic-issue, so that the user has one more issue type option (=Request) to choose from besides the predefined options: task, story and bug:

I already checked the "Issue type hierarchy", but this doesn't seem to be the right admin page since it didn't list the types "Bug" and "Task" (which is shown above in the dropdown).

Where is the parent-hierarchy of "Epic" (to its children: Task, Bug, Story) defined, and can it be extended by additional Issue Types?
Thanks!
