well, maybe I can describe my problem differently.
What I want (and don't know how) is to show/filter all my races I did in Leaderboard Challenges.
Now - if I want to know with which cars I challenged at -for example- Bathurst Raceway - I have to filter TRACK -Bathurst and than annoyingly select one car after another to see if I rode it with all my cars.
Sorry for my english, hope somebody will help.
