Hi
We are looking to create a dashboard gadget which consolidates all children and grandchildren issues underneath an initiative.
As per below snip, Level 0 FCI- 28 CI Team - BAU is the item I am creating the dashboard for. We then have five disciplines under this Level 0 item which I want to create a filter where I have all the items contained in each discipline but when I report in the dashboard, I want it to group at the discipline level rather than it grouping back to the epic. Can this be done and how?
I have Jira Premium with the Custom Charts addon and also the JQL Search Extensions addon.

Thank you
