That needs researching. As far as I know you cannot assign one team kit to another....Yeah, I know that a texture replacement makes the job and you can easily swap classic kits with 4th set, but I meant how to assign a classic kit to different team.
For example - we have German national classic kit - but I want this slot to be assigned for Torino (for instance) and replace classic kit with Torino's third.
I know it's possible as I sow similiar mods related to that on FIFA Planet. A guy has created various kit sets for 3rd Bundesliga teams and used classic teams kit slots instead (re-assigned).
Maybe Andy would enlighten us on this matter.
Gonna try it, tomorrow, with classic kits. If it works, then we could have something.
