Funny though, letter "ä" after channel name, ie. CNNä_B and CNNä_U does the trick. I guess some other letters/marks might do the same but this wiped "-" away from my remote. You won't see it in the channel name when downloaded to remote... So first close the Configurator and then (re)name channel (in your channel folder) as stated above and then add it to tv/radio channel in the Configurator. Don't pay attention that it still shows at this point in the Configurator, you won't see it anymore when you download it to the remote. Give it a try...and please comment here if there's another way to do this.
