Allow fuel and tires change in stock race

One problem with FM is we can’t do championship with full stock cars because we can’t choose which amount of fuel or tires we take.

If I launch a lobby with no tune allowed, I can’t choose my tires or fuel (My game is in french but you can see that I don’t have any access to that feature)

How to add it to the game :

1st idea : Just saying that changing the tires (hard, medium, soft or wet) and changing the amount of fuel in the car aren’t tuning

2nd idea : When we have the tune of an other person on the car, we can choose which tire and the amount of fuel we want in the car. So why not just saying the stock tune is tune made and shared by the game itself and it will allow player to change tires and fuel
