I'm new to my organization is has started to adopt Jira to manage the delivery. They started using the default work type structure and I was suggesting for a few Key boarder initiatives to add an additional level to help track and manage their work, but was told by the admin that they would have to apply this across the board and could not just apply to a few of the projects.
Looking for guidance if there is a way to just apply the changes in a way that would only affect selected projects to assist in the transition process.
New Proposed Structure:
EPIC < Feature < Story < Tasks
