ProtoTypeK7

I have a question if I may; when trying to setup and use the factory module, is there any way to dictate what skin a spawned unit will utilize? For example, if I wanted spawned infantry to use a winter livery or a spawned tank to use a desert livery, is there an attribute setting/command that specifies that? As of my present understanding, I can have a factory zone spawn a specific unit such as Soldier M4 GRG but am aware of no method to dictate that such use a winter livery for example...is such possible with the factory module? Thanks in advance.
