ClearNav - Upload SeeYou Tasks?

I'd like to upload tasks I've created in SeeYou to my ClearNav. The ClearNav documentation that I can find (online on ClearNav website, plus the older partially completed manual by Paul Remde) don't seem to address this.

I've tried creating a .cup file with waypoints and a sample task, then uploading that file to ClearNav. The file uploads and is selectable in ClearNav (as a Waypoint file), but I don't see the sample task the file contains.

Has anyone done this, or know of other ways to get tasks uploaded to a ClearNav flight computer?

Thanks,
- Frank
