Crate function with autoload needed

I am coming off a iDJ II, I really love the crate function (a playlist where the tracks disappear once loaded) then have the autoload next track from the crate option, this would function like the iDJ II.
Numark was really proud of the crate in the iDJ II, I am surprised it was not implemented into the iDJ Pro.
(BTW: one would also need to import a playlist into the crate.)
