So when a race day, owner would be able to do an race that is only 25% long, this would work for leagues with 50% and 100% races but leagues with 25% races already wont be able to add a sprint race, of course owner doesnt have to turn this on, he could turn it on but he doesnt need to, Sprint would start maybe 2 hours earlier and owner will also be able to decide if main race should have its on quali or starting grid is the result of the sprint race...
good idea but it will most likely not be implemented, i'm pretty sure they rejected a similar idea? i might be wrong, but also the resources and the amount of programming needed is a damn lot
