I'm creating a stadium titlepack and I just want to add new tracks to the campaign. So there is no problem to add tracks to difficulty white, but I don't know at all how to put a track in an other difficulty like green ect. Moreover, adding to much track to white difficulty makes bug and I can't click on the tracks to play them.
I've been searching on internet since two days, but I didn't find or I'm just to stupid to understand

Sorry for my english if there's mistakes :/
Oh and sorry if I placed wrong my topic, I'm new and I didn't find

Have a good day !
