Mid-song Transitions (At Markers or by Command)

At the moment, transitions only function at the end of a song or a certain length of time before the end of a song. I was wondering if there was any way to begin a transition into the next song while still in the middle of the preceding song other than doing it manually with the slider.

If there is not, one idea is for there to be an option for a transition to commence once the song has reached a set marker. Another idea would be for there be an separate button for the purpose of starting the transition anywhere in the song.

I support transition at set marker idea. Maybe cue#3 can be used for that if in automix mode. As for manual i think that autoslider button does that. Correct me if i am wrong.
