CDJ 2000 memory cue loop help!

I have read numerous posts with similar titles but haven't been able to find a solution.

I have a CDJ 2000 what I am trying to accomplish is a way to play the loops i have saved in the memory cue (not the active loops because I understand that those are only for the nexus?)

When I say play those loops I mean to activate them before the song gets to that part and then when it does have the song start to loop without interrupting the song. Is this possible? Otherwise what is is the point of having the ability to save loops to the memory cue, maybe I am missing something!

thanks!
