Depending on the software you use you can do it whether or not the actual CDJ has any cue point support. Most of the major softwares will allow the addition of an accessory controller (such as something like a Reloop Neon) that will add cue points into your setup. If you have an X1, I’ll assume you are looking at Traktor, so it should all just work.
As a side note, if you’re looking at the CDJs as standalones, it gets a little more complicated. The SP1 is currently the only unit I’m aware of that allows you to do this – and only with specific models of CDJ I believe.
