bing map- 2 pushpins same co-ordinate workaround?

I have multiple locations that I show on the bing map via pushpins at specific lat/long co-ordinates. There's a situation where 2 pushpins have the same co-ordinates and both are stacked on top of each other. So the user cannot click or see the pushpin below. Please suggest workar开发者_C百科ounds or any ideas.

The general approach is to display some sort of cluster icon to let the user see that there is more than one location represented by that pushpin, and then present a disambiguation box when the user clicks/hovers on the pushpin to let them choose which location they want to select. This is the same approach as you would use to cluster pushpin data on the map - aggregating several distinct items of data into a single cluster unit.
