The location plugin was built to do exactly this. Even down to downloading the init.xz and bzImage from the rekavant location.
Goto FOG Configuration -> FOG Settings -> Plugin and enable plugins. Then go to the plugin page and choose activate plugin. From there choose the locationbplugin. It will install kind of. Choose install plugin and select location. It will ask to install itself. Then you will have a new menu option available. Go to the location page and set up you locations.
