How to show child tickets on kanban board, next gen project?

[Patrick Walters]

We have our kanban board for a next gen project and have added child tickets but they do not show up in the board, only as an icon on the parent ticket.  Ideally we want to keep this hierarchy of tickets that lead back up to an epic but show them all so we can get a better view of what is going on.

The following suggestion may be inappropriate to your organisation but if you were to allow the support technicians to pick the next priority ticket rather than assign you would be able to focus on establishing the priority of tickets at all times and always making sure that the next ticket was picked up by the next available support technician.  This would then give you a clear indication of the number of tickets not currently being actively worked on by a support technician, whereas from my understanding of the current situation you need to total each support technicians tickets to get such a metric.
So when you complete triage you would assign the ticket to either noone, a user for the queue or potentially if a single support technician has the skill direct to them.

I don't dislike your suggestion, however I have a couple of questions. 1. Are you suggesting people manually go into the "triaged" list and pick their own tickets? 2. How would you prevent agents from "cherry picking" the easy tickets?
