Yes there is but it isn't straight foward.

First you have to create a series to decide what cars and tracks are available. -> https://steamhost.cn/steamcommunity_com/app/365960/guides/#scrollTop=541

then you need to use use the rfactor log analizer. With this you have acess to all your race results and can create champhionship with your rules (for points). Then you just added the race results to the champhioship you created. -> https://steamhost.cn/steamcommunity_com/app/365960/guides/#scrollTop=0
