I don’t, really. This is one of the main issues. Stuff like cue points, loops and such are still very much proprietary. Meaning the way those things are marked are DJ software dependent. And while Cross has an iPad version of the software, I don’t think you can carry over the cue points (pretty sure you can’t actually). Traktor had that kind of integration in the early days of their iOS version I think, but that got broken really shortly afterwards and is no longer operational if I am informed correctly.
Rekordbox would work, but you’d have to go to RB DJ-ing which isn’t much fun unless you only play club gear or have an XDJ-RX.
There are some tools that helps migrate cue points and metadata. But not from every platform to every other platform.
Also that would be a b*tch to do every time you did a few tracks on the road.
