Some jokers are necessary to be used in groups, some separate. All depends what is written on homologation documents of those.
So there is no easy way to track all the cars like they are without seeing their gold books. And not all cars have gold books and some have not recently updated ones. Most of the time they update the gold passes only on ERC or WRC events. So if car drives only national events you can just guess what's inside.
