Add support for "One hop query" relationships aside from parent-child

My company uses PBI's for deployment tracking as well as specific code tasks (we then use "Tasks" for the different aspects of that given PBI. e.g. Dev, San etc...). I'd really like to have taskboard that would be focused on the releases but where we could see the PBI's for each release. See image for my current query. Would it be possible to have the taskboard display the query results as if it was a parent-child relationship? -Thank you!
