I don't think there's an easy way to accomplish this. I do an offline, solo series and couldn't find an easy way. I used the Tuning menu to create AI drivers with names I gave them. Here are more details. I chose one car from the mod as a "master" and in tuning created a directory based on that car. I then created 21 skins based on that master for the AI cars and moved them to that directory. Then in Tuning, you can cycle through the skins and create a new driver for each. You can give each driver a name you choose. You can also edit the AI data for each driver. You then end up with a folder for each driver you created. I also created my own car and added it here, too The next step was to create a RaceEvent, include all the tracks and plugins and add ONLY the the original car and driver from the mod that I used. That means the RaceEvent will have only one car and driver. Now, when I load the RaceEvent, I go into the Session Settings and tell it I want 22 AI drivers. It will then use all of the drivers I created in the Tuning menu and give me a field of 22AI cars plus myself. It includes the "master" in the group, but I can use the Boot button in the Standings menu to eliminate him. It's a little clunky but it was better than editing the mas files directly and possibly having all of them blown away when the mod was updated.[/QUOT
