F1 2015 Weather on the PS4

[lhutchy]

Ok so I know when racing these games we all want to keep it as real as possible, but as I was getting into the championship season after you select the race length (100% all the way), you get to the assists and race option there are the greyed out that say the race length and that. There is a option there for 'weather' which is greyed out. Is there a way of changing this for the championship or just for stuff like single race?
