How to display multiple markers in Views?

I'm having a difficult time discovering how to display multiple markers on a single map. I set up a View with one of the map overlay fields. The problem is that a separate map displays on the View page for each Node with a coordinate-enabled gmaps CCK field. So, I have a view with 10 maps. Is there a way to combine all of the gmaps CCK field data across multiple Nodes into a single map? Or, am I misunderstanding how gmaps works.
