Bit of background - I have several Epics that have sub-tasks - sub-tasks are used to record the work and various things to be done to progress the Epic, similar to sub-tasks for Stories. Each Epic in my project has the same subset of sub-tasks.
This is what I am looking for:
I want to have a view of all Epics showing a count of sub-tasks grouped by sub-task status so I can see how many sub-tasks are To Do, In Progress or Complete and understand the progress of the sub-tasks on each Epic.
I also want to be able to pull a list of all Epics that have a sub-task in a specific status with said sub-task displayed with the Epic, so that I can manage sub-tasks by type of work in groups.
