Hello all
Is it possible to get a 4-layer system in Jira starting with an Epic >> Feature >> Story >> Sub task
I have now created a solution in Plans with an Initiative as the top layer then you get the Epic , Story and Subtask.

But I would like to work with a Feature because this most closely approaches the Agile way.
Epic for the duration of 1 year
Feature for the duration of 3 months or 1PI
Userstory for a task
Subtask for performing a subtask
I would love to hear your experiences
