Similar to it is in Jira Software where you can create tasks/US under a project and optionally nested under an Epic, I'd like to create in Advanced Roadmaps US/Tasks under an Initiative, but without linking them to an Epic.
In the end, the objective is that I, as a project manager, can create/plan tasks under initiatives that at a later stage each development team can assign to their own Epic. This considering that the current hierarchy level I have configured is Initiative - Epic - Task/US
Is this possible somehow?
