Board Game Arena

I've been playing a lot of Cartographers since the launch of the Heroes expansion and I love the amount of variability it brings to the game. Hence, my favourite way to play is to randomize everything and face a new and unique challenge each game. The only thing I've been missing, however, is the option to fully randomize the map setup.
I can chose to have "random A or B", so it should be easy to add an option for "random A-D", shouldn't it? It would be much appreciated.

Thanks for implementing this great game!
