I have a dashboard containing multiple views. The first view provides a summary of totals which when clicked on filters the other views on the dashboard via dashboard actions. The issues I've got is best explained in the illustration below.
(I'd attach a work book if I could but for some reason I can't get it uploaded through chrome, IE10 or IE11 or IE10 in compatibility mode/IE9 mode....)
I just tested this and think I have what you are looking for. Select the region on your dashboard and when publishing to the server just make sure the Show Selections box is checked. Worked for me when I viewed my published dashboard in Chrome.
