At this point I am also working on a possibly möst realistic grid for Nürburgring 24h. I want to ask if it is possible to make a subfolder with the cars I wanna use for that so I can access and edit the grid easier, since I have so many cars by now!? Not sure - so the experts are being asked again. The "category" function in CM might be a solution but also not sure how these subcategories work at all. Thank you.
