Zombie plague 4.3 class/item restriction
 

Hello, I would like to know if it's possible to set a Limit to and extra item and/or a zombie class?
I know it is possible for version 5.0 but I would like it for version 4.3

Exemple:

I want to use this extra item:

Is it possible to make so only X ammount of players can use/buy it this per round?


Also, can we do that with a zombie class too?
