Automix building by DJ "slot"

New user just starting to play around. Would love if you take the automix feature to the next level (prob needs your energy level/etc future features first) by having some presets to arrange mixes for various DJ slots and genres. What I mean is an opener, headliner, closer, etc. Would really help save time and also open up some other combinations you may miss with your library. Also related to this, having an option to specify how many decks. Would love to see how your algorithms find awesome acapellas or other tracks to lay over the others in a 3 or 4 deck setup (For EDM)
