add songs from library to itunes radio

This might be a stupid question.

Is there a way to mix music already in your library with the radio station you aare building/personalizing?

I am a j-pop/k-pop fan and while I am happy that my radio station does actually play 85% Japanese/Korean music there are many of my favorite artists not included in the stations (I assume licensing issues). So if it once in a while pulled from my library so I can hear my favorites along with the new artists I'm discoveing that would be great.Just curious if it can, I love it so far - if it can't that won't destroy it for me or anything I'll still use it. Once again just curious.

Hopefully I am making sense....I do tend to ramble.
