WCW question

You know how most guys in TNA mostly the young ones and some of the older guys can go and do Indy shows. Was that allowed at all in WCW? Could the go work in Japan or make quick money doing an Indy show or were they strictly WCW only. I also remember hearing Vince would let some of his guys do indy shows back in the early 90's. I know he also lets some the bigger guys come into the developmental territories and do run ins and beat up some heal or whatever.

But did WCW let the less used guys work some indy shows?
