Calendar size customisation! Please patch it in F1 25

We have had for years 10, 16 and 24. Its about time we get more.

Especially now that there are so many races on the calendar. There should be a patch later down the line that allows us to have 17, 18, 19, 20, 21 grand prixs. 24 can sometimes be too much and 16 too little.
