In our organization we track our development issues in below format, where Master Epic is our parent issue
Master Epic -> Linked to (Is child of)-> Epic
Epic --> Linked to (Epic Link) --> Stories
Stories --> Has sub-tasks
We can see Epic has "Epic Panel" where we can see the sum of time tracking and attachments of all stories and sub-task under it.
We need similar feature for Master Epic too. Please guide how we can have this feature.
Thanks
