You can only have ONE supp map on your SD card. You can create multiple files with the same name, but u have to create folders for them. When you want to use that particular mapset, then you rename the one in use and copy over the oneyou want to use. It's really stupid of Garmin to have the conventions set up this way, but that's what we have to go by.
