Customizing Issues in Epic Columns

[Liz Debes]

I want a way to show that an issue has been flagged (impediment = yes) when looking at the Issues in Epic section. 

I am looking if there is a away to customize what displays in the columns under the section within an Epic that is called, "Issues in Epic." I want it so that other users who have view access and are not monitoring the specifics of several different projects (like in a dashboard or on a board or in a saved filter) can see a high level view of stories related to one project. We use Epics to house related stories on one specific project/initiative.

I would *love* this table to be configurable but have to find a app that allows this to be done.
