Is it possible to clean up the sprints shown in the list when filtering in the advanced roadmap? Although I'm setting the filter eg. to "all future sprints" (and I don't mark "all completed sprints" or "all active sprints), I have to scroll through all released and active sprints to be able to choose those future sprints I'm interested in. So I'd like to be able eliminating those sprints I'm not interested in from being shown
