Has anyone created or know of a waterways style file for use in GR2Analyst?

We use GR2Analyst to view weather radar data and I was looking to add the OpenStreetMap waterways file but an accompanying style file is required to display the data. I was wondering if anyone had already created on or if anyone knew of one available somewhere that had already been created that I could use before I attempt to create one myself (which I have no experience yet in doing).

Thanks, Hunter
