How to display a specific subtask and it's grandfather initiative.

[stefan_wilke]

We have a structure with Initiatives/Epics/Story/Subtask.
For our checklists the subtask is under the EPIC.

So my question is how can I present a list of initiatives and get one specific subtask.

I've done a filter that finds all subtasks:

project = "BSS" AND  issueFunction in linkedIssuesOfAllRecursive("filter=113594") AND (text ~ "F3 Usage of Protocol" AND issuetype = Sub-task)

This uses a subfilter to find all initiatives for a specific release (filter=113594)
And finds all subtask using relevant text.
But I need to present the Initiative that corresponds to the subtask also because all subtask are called the same....
Presentation in Dashboard/Confluence or even export file format is OK.
