Any advice on combining a file for the Indycar Nascar weekend? I assume I'd just remove the NXT banks and replace with Nascar? I'm really only interested in Indycar and the Cup series. Thanks for putting these files together, they're very helpful for us newbies.

Hi. You are showing Next Race: Firestone Grand Prix of St. Petersburg on 3/7. Is that a copy/pasta glitch? Thanks for all that you do.
