Automix starting from the middle of a track

Hi guys, I just found this software and sounds like its what I need for a party.

  1. I am just wondering in regards to the automix feature, is it possible to start playing a song from in between rather than the start / stop of the track.
  2. Furthermore is it possible to have random transitions where the next track starts from the actual start and sometimes the next track starts from the middle?

Edit3- Also wondering whether any of these advanced automix features which are available on the windows platform is also available on the Android platform
4-Finally, is it possible to que using spotify and manual tracks in the Djay for windows? Thanks
