Yes, at the data management on the options.
Ontopic, one option would be the one mentioned above, to use the data available on the disc (mainly textures) and just create the level itself and make it downloadable. Another one would be to procedurally generate the textures, if they don't want to use the same on the disc. They upload the code, and the Wii creates them on the fly... but this one isn't as easy.
