Upload/download .gpx files

This requests addresses the uploading/downloading of .gpx files that are not created via TRX Trailhead software.  Currently the user has to upload/download .gpx files via SD card.  Why?  There is a perfectly good USB cord this can be accomplished through.   Updates can be done in this manner as well, vice the current wifi method.
