I've created a geologic units map. Each geologic unit is composed of multiple placemark polygons. I currently have the same geologic unit description repeated in each placemark composing the geologic unit in order to get the functionality I want (click on the polygon and get a description).
Is there a way to include the geologic unit description once in the KML file and use it on multiple polygons?
Here's an example of what I currently have:

I figured out how to do it with BalloonStyle Text. Is this the only way or is there another/better way?
