Multiple traktor users on 1 traktor s2/s4 setup

Hello guys from NI.

We happen to have this problem. We form a dj crew (3 of us) and play some gigs from time to time. Everyone has a traktor s2/s4 setup at home, because we wanted to practice some tricks at home and show them during gigs, but right now it's hard to do because:
- Every one of us has a setup at home.
- Every setup is configured in a way the one likes (effects, layout, font size, pitch range, pitch fader behaviour)
- When we meet at the gig, we have to fight with each other which setup will be used during the night, and that's wrong, because everyone has to drop some of the routines they learned at home, because the setup we are using has a different configuration.
- We end up just limiting us to using the basic features of traktor, not making all the nice and wierd stuff they show on youtube

To make things worse - we are using just one traktor s2/s4+laptop setup - because it would be stupid to bring all 3 for all of us, it would just take a lot of stage space. So we have to copy our music onto each others collections and ruining it with unwanted garbage. I don't want to have my friend's tracks there, they don't like it either, mostly because we do pay for them and buy them for ourselves - not the rest of the crew.

What I'm trying to say is right now the traktor thing is getting too peronal.

I have come up with an idea that would make traktor more usable in clubs, where there are a lot of djs and just one setup:
- At home i would create a playlist for that night as I always do
- I would click "export GUEST TRAKTOR PLAYLIST"
- Put my name on the whole export package and the package would include all my settings (effects, layout, font size, browser layout, pitch range, eq behaviour, pitch fader behaviour)
- the package goes to the usb stick
- At the club, where S4 (maybe S4 MK2) would be, there would be an USB hub
- With the traktor running, after putting the stick the software would recognize that it contains a GUEST TRAKTOR PLAYLIST with all the settings and let me assign a key for that. Maybe there could be separate keys for that on your new controller. If the S4 MK2 would feature USB hub with numbers HOME 1 2 3 4 and separate keys for those, by putting a stick into hole 2 it would activate the 2 button. By pressing this one I would see my whole layout as it was at home (but with the decks still playing).
The tracks on the stick would not be imported to the main collection, but appear in the "guest collection" without the need to analyze them again. Owner of the setup could always click HOME button to see his own setup and so on.
