CSM Tweaker question

Hi..I am wanting to compile a mod with full carset subset option where it loads all the cars and anim and helmets etc for rounds 1-17, to save me exiting back to CSM to change the track when i want to do the next race.

My problem is that i have some cars which have different tweaker positions for some tracks, just wondering if you can configure the vars in some way that you can get different positions for each race without exiting the game and choosing the next track in the CSM menu?..

Thanks
