title: display multiple pin balloons simultaneously (pins share common title text)
body: <p>Is there any method that will allow multiple Google Map location pins to display their attribute balloons simultaneously, when all the pins share the same text string in their pin title?
  eg I have plotted the addresses of 3 branch offices of a business on a My Places map. Each branch office has the same 'business name' as their main pin title. When I click on any one of these 3 pins, I want all three of them to <strong>simultaneously</strong> display their info text balloons.</p>
