Pipeline,
please do not waste time on this. Even if you find a simpler way, it would not be an easy one, because there would be no option to audition these midi phrases. I think the only place you can audition these midi styles are through stylepicker. Would make sense to be able just to copy individual tracks from picker directly to mixer track.
However, I would prefer a universal tabbed picker for ALL tracks: RT/RD/Midi/Loops. ...and be able to choose these style midi lines right from mixer.
I think it is a solid candidate for wishlist.
