How can i map Traktor Kontrol X1 fx3-fx4 ?

[SorinTheSpy]

Hey guys, i was wondering if someone could help me here,

I use 2 Traktor X1 for mixing and i want to use use 4 fx for each deck without touching the laptop, is there any way i could turn on the fx3-fx4 on controller one and fx1-fx2 on controller two ?
I would like to make a mapping for Shift + fx1 and Shift + fx2 and with this commands to turn on the fx3 and fx4
Is that possible or i expect something what cant be done ?
I tried to map it myself but i didn't get to far

Add FX unit on command > enable Learn > hold Shift and press the button you want to apply command for
