Hi W.

Do you want to copy the exact track or you would like to have the piano track in the Guitar/melody track so you can use another piano in the piano track?

If you want to use a second piano, or have a piano in the guitar/melody track, just assign (generate) a real track in the track you would like. So Under guitar, select assign real track and assign a piano track.

Maybe this will work. Hope I am able to answer your question. Let me know if you need more assistance.
