Cue to a point of all songs based on a % of track length on automix

I reckon it woulying on automix be a great feauture that when it is playing on automix, that you could select a point where it starts each song (eg 20% in the track). ie if you have a 5minute song, it would start playing at 1 minute - this would be great if you dont want to be next to your phone the whole time, and this way you can get the songs to start when they are at chorus’s/peaks etc (eg if you have extended electro tracks, but want the song to start when its built up - selects 15% or whatever you like!
