Hardware unlock for all connected devices?

Dear all, I recently tried to use my NXS2 setup with the performance mode in RB6 and found out, that they are not hardware unlock devices and therefore would require a monthly/yearly plan. If I switch over to an XDJ-XZ the performance mode would be unlocked. My question now is, does this unlock only work for this one device or could I connect a CDJ2000NXS2 as a third deck in addition to the XDJ-XZ and all three devices would he usable in performance mode, as long as the XDJ-XZ stays connected? Thanks in advance for clarification
