That is indeed an idea, thank you for that solution.
The thing I was thinking about with this question is, you already give a station a name under Radio called Title. Why not use that for the purpose I am looking for as a tag. It must be a different title in the MB software itself then song title for example, it "just" needs to have a seperate tag.
But I could be totally wrong about that ofc and "it just" might be a lot more difficult to program then I am aware of.
