Hi there i am experimenting with building my own tours.  How may i use an already created placemark id in a <gx:FlyTo>?
example placemark
<Placemark id="vbhpin">
      <name>Elkridge Volleyball House</name>

      <Point>
        <coordinates>-76.7058,39.2155,0</coordinates>
      </Point>
</Placemark>
I'd like not to repeat coords in my kml code. is there a more modular way of doing this... so as i can call a point.. multiple times.. and only have the coords in one spot?
