Multiple cars awarded from street races

Kamfad how do i make it so when you complete a street race, more than one car is given? i tried changing it to say "streetrace" but it only allows one award at a time

Addy Hardcoded and impossible to change unless Donut Team create a hack which allows it to be changed.

Kamfad oh ok, that sucks edit: a function that rewards you for 100% completing a level would also be nice
