JQL Filter to show only the 1st substask of each parent

[Alexandra C]

Hello, 

My team is using BR issues and subtasks to follow project deployments.

To ease the team members dailywork , I've created a dashboard to show each opened subtask assigned to current user based on the following filter:

project = XXX AND issuetype = Sub-task AND status in (Submitted, "Resolution In Progress", "Task Postponed") AND assignee in (currentUser())

But I would like to go further by showing only the 1st opened subtask of a given parent in order to help people concentrating on their most urgent task of each project.

Thus I would like to move from a result like : 

subtask 1 ( parent A)

subtask 2 (parent A)

subtask 1 (parent B)

subtask 2 (parent B)

to 

subtask 1 ( parent A)

subtask 1 (parent B)

Any  suggestion?

Thanks for your help

JQL simply finds issues that match a criteria, it has nothing to say about how you report on the list of issues it finds for you.

I'm not aware of any gadgets that limit their results list as you describe.
