Transition and/or trigger issues

Let me start by saying I really DO like this app. I just downloaded djay Pro for iPhone. HOWEVER, I always find the same issue when using the Automix function. I will try to explain below.
I cannot find a way to make the next song start a little after the transition already started. For example, I want to set up a transition of, say 10 seconds, and trigger the next song 5 seconds AFTER the transition started. In this way, I would be able to hear both the last song fading out and the next song starting half-way into the transition. I can’t seem to find a way to do this.
As it stands, regardless of the transition duration, the next song triggers BEFORE starting the transition, and the listener loses the very first few seconds of the next song.
Let me be clear: I want to be able to hear the last song fading out AND hearing the next song right from the very first seconds also, pretty much like a regular mix you can hear on the radio.
Is there a way to accomplish this?
