Show estimate calculation in scrum board backlog when creating an iteration when any view is selected

Currently, when you are in a scrum board backlog creating a new iteration, the estimate points only calculate when the "Backlog" view is selected (or when the Estimates field is added to a view). It would be helpful to have the total points/hours estimate calculate as you select tasks to add to the iteration regardless of which task View you're looking at. If the estimates column is not in the selected View, the points show as zero.
