Scenario:
I have a Service Management project for support. When needed we escalate internally to other teams by creating a ticket on their projects and linking them together.
Need:
I want to create a filter where I display my Service Management support tickets in statuscategory=!DONE AND where the linked ticket is also in the same status category. Effectively showing all my support tickets that are still open but skipping those where the linked ticket has statuscategory=Done.
