I'm placing numerous pushpins on a map using the AX control. I sometimes have several pushpins at the same address. I'm wondering if there is some unique identifier of each pushpin that I can pass through my program to access a specific pushpin from other areas of my program. I've looked through the MSDN information, but maybe I'm not looking in the right place.

As an example, I place two pushpins at 1234 main street, each representing separate shipments. From my program, I select shipment number 2, I want to hilight the pushpin associated with that.
