Hi @MarkWheeler ,
I would suggest defining a new hierarchy in the Issue dimension. The benefit of that is less MDX as the measures from lower levels would sum up to the higher levels. See the linked post for a detailed description on defining custom hierarchies in the Issue dimension - Issue Hierarchy - Linking Not Working - #4 by gerda.zandersone.
And also the eazyBI documentation page - Additional Issue hierarchies - eazyBI for Jira.
Then you can try creating a similar report to the one in the eazyBI Demo account - Issues - Jira Demo - eazyBI. But instead of the “Epic” hierarchy, use the custom hierarchy.
Best,
