Query to produce list of epic child items from a query to produces list of epics

[John Mimms]

I am using Cloud Jira and Confluence.  On a Confluence page, I have a table with columns for Capabilities, Epics and Stories.  The intent is to show the capabilities, related epics and related stories in separate columns.  

I have a simple query in the capability column to select Capability issue types based on the fixVersion and label value (Capability Query) and produce a small table of the results.

I have a query in the epic column that will select the issues that have a parent link to one of the issue from Capability Query (Epic Query) by using "issueFunction in linkedIssuesOf("Capability Query") and produce a small table of the results.  I am concerned that this may pick up epics that are related to one of the capabilities, but is not a child.

I would like to have a query that will select the issues that have an epic link to one of the issues from Epic Query.  I found I cannot nest issueFunction in linkedIssuesOf("") statements.  

Is there a way to select the list of stories that have the epic link that points to one of the epics in the list of epics in the epic column?
