That is a good idea.
Until then, you can make your own playlists of radio stations and cut and paste or put the list in any order you like.
I noticed that MPD will play any list in any order (as long as I don't screw up the urls). This way I can organise my radio playlists on my PC, and then just paste the content over to RuneAudio in whatever order.
As a plus I can then use my remote (directions provided here by XPLOD), and "tune" up and down through the stations just like on my receiver...
