XML Google Maps – Clustering Placemarks

Hello, I am inserting a url into a post using the xml google map plugin to display a map. It looks like the following:

<ahref=”url.kmz”> Map

The map functions within the post. I would like to cluster the placemarks together to appear as a group when the map is viewed from a certain distance.

Is it possible to do this using the xml google maps plugin? If so, do you know what it would look like? Thank you.
