It might not be as easy as just adding the game to jqe360.com. System link for games that is not supported is greyed out in the menu of Freestyle Dash so we might have to wait for a new Freestyle update.
DISCLAIMER: I could be wrong tough, maybe Freestyle always checks online when starting a game if it's supported by LiNK. Freestyle always seems to know if BO2 has got a new TU for example...
