Give us to desactivate vanilla biomes at generation as we can with new Frosty Planet DLC:

Hello, 

I would to be able to choose my asteroïd and activate / desactivate as well vanilla biome as new format of dlc like Frosty Planet.

For exemple, on SO + FP classique mode, I have generate CERES but i don't want to have forest biome or bee's biome and play the full experience / ecosystem of Frosty planet without alternative (like vanilla trees or dreckos on the map or via portal).

I think for later on the dev of the game with multiples DLC it will be an advantage to give to the player the choice of the biome he want on his asteroïd, vanilla active by default and then add or remove biomes as we wish to play.

Thank you !
