matching/ related playlist CDJ Model compatibility

So there is a feature on Rekordbox which allows you to 'match tracks', and create a 'related tracks' playlist which is similar to an intelligent playlist as it can generate track suggestions based on what a deck is playing. 

You can export this and load it onto a CDJ but it is not documented anywhere which CDJ models this is compilable with. Far as I know the following models support it;

CDJ 3000s

CDJ 2000s NX2

Is it on CDJ 2000s/ NX1? What about older models with the right firmware update?
