Hi brainstrust
We have a structure where we have a JPD Idea which is implemented by delivery features, that are parents to delivery epics, which have children. The JPD idea sometimes might be linked to a JSM ticket which has subtasks.
I would like to find all time that is logged with Tempo time sheets on all issues (including subtasks)
Is that possible?
Note: here is a diagram of the structure of tickets.
The first two are "JPD" projects, so there is no time on them.
Everything under JAC4-4 could have time applied to the issues (including sub-tasks).

I tried:
issue in linkedIssues("IDEA-1209")
That just returns JAC4-4
When I tried:
issue in linkedIssues("JAC4-4")
It returns - IDEA-1209, FEAT-303, DISCOVERY-3
When I tried:
issue in linkedIssues("FEAT-303")
It returns: JAC4-4, CAI-5197, CORE-4371, DIG-15912 but not the subtasks.
I am not very experienced with JQL, so would appreciate any guidance thanks.
