JQL and display: How to get multiple results for issues that MAY have multiple sub-tasks?

[Jarrett LaBarge]

I have Issues of a certain type that MAY have subtasks.  I would like a filter to get the Issue information as well as information from each of the subtasks, if they exist.  If the Issue does not have a sub task, then I want just the Issue data.  We have the ScriptRunner plugin and we can get data we want but we are unable to get it to display appropriately thus far.

For example:

Issue 1 has 2 subtasks

Issue 2 has 0 subtasks

This is what I'm looking for:

Issue Key  | Sub Task Key | Issue Summary       |  Sub Task Summary

Issue 1      |  ST 1              | Issue 1 Summary    |  ST 1 Summary

Issue 1      |  ST 2              | Issue 1 Summary    |  ST 2 Summary

Issue 2     | <blank>           | Issue 2 Summary    | <blank>
