munger2k on "[Plugin: GD Rating System] Custom page"

Hi, is it possible to use the plug-in without using the post id as the defining factor to store/display ratings?
For example.. I have a single page with a custom template used as a player profile, the page is populated from a database based on a $_GET from an id in the url.
eg, wordpress/player/?id=1 wordpress/player/?id=2 wordpress/player/?id=3 etc etc.
As far as WordPress is conceed, whichever player I'm displaying would technically have the same page id number so the plug in would always display the same rating.
Is there a way to store and retrieve a rating by defining a custom variable instead of using the page/post id?
