control of time of song

Would really like to be able to set the time a track plays before next transition, obviously would need time to be variable within a range to enable the algorithm to do its thing re finding the best transition point but being able to set a parameter of 2 to 3 mins per song etc would be great for faster mixes. Thanks and love the software btw and so impressed with the teams update rate. Saw you guys at ADE and you are lovely people.
