Arno's right, you have been able to do it for years. The trick was knowing the chords of the measures you are transferring and either transposing to C major, or setting the chord in the composer, which is the same thing. From the 6k you could transfer 2 tracks to the pads too.
The big advantage of the song to style disk or the EMC programs is they automated this transposing step and often came out with reasonable choices of measures and fills too. A little tweaking in the composer and you get great composers tailored to the exact song better than a generic style.
