The system can not have a Sprint Backlog, because the saved search only works for Product Backlog.
My developers are confused because the Backlog items are of Sprint and Product.
If I have two Sprints running at the same time, the backlog will appear the Issues for the two sprints, making it difficult to view a prioritization.
How could I filter my Backlog for the selected Sprint?
Even because the Product Backlog is solved with Saved Search in the Issues list and I do not need to see all product Issues in Agile Board.
