I think I am trying to achieve something simple but I really can't see how to do it?
I can see that issue type schemes indicate which issue types a project can have. But how can I restrict the child issue types that an issue type can have?
There seems to be the assumption that an epic can have any issue type as a child, but I have created some new issue types that I do not want to be children of an epic - and I do not want to be able to create a Bug as a child of an epic.
How can this be achieved? Given that you can create new issue types, there surely must be some way to restrict where they are used?
