is there any way to merga all skins in one ?

i am working on freeroam server, so i want all skins to be merged in one line means:

AddPlayerClass(0 .. 311,410.6863,2532.9053,19.1484,142.4334,0,0,0,0,0,0); // playerspawn

i mean any way like this so i can have all skins on the spawn selection place?
