I know this is a bit of an old question, but I wanted to post a workaround in case it may help others.

I create a separate team with no members that is something like "Quarterly View" and then under "Iterations" for that team, I just add the parents or whatever level I would like this kind of filtering. Then when you build your query, you can make it "Iteration Path Under @CurrentIteration [Project Name]\Quarterly View".

This should give you a best of both worlds because you can still work with more fine-grained sprints while making queries/view that are built on any scale you would like.
