I am looking for a way to create a new "Initiative" issue type on Jira, and manage the hierarchy of the levels. However, in all the tutorials I've come across there is a reference to the "Advanced Roadmaps" menu, which appears to be available only for the Premium plan.
I can create new issue types, but I cannot figure out how to relate them in terms of hierarchy.
Is there any way to manage the hierarchy of custom issue types on the Standard plan?
