In 0.15 we now have map presets when generating maps. Is there a way you can reconfigure your mod so a player can chose it as a preset?

Rather then every world generating the World map when started; only maps started with the World Map preset would generate Earth.

Sadly as far as I understand, the presets are just settings for the build-in generator, so I can't change that.

I could maybe check like the name of the chosen preset, but then again, I don't regenerate everything, so most of the settings still apply of the chosen preset. I just change the terrain, nothing else. So if you choose a preset with a lot of ore, there will be more ore on my map as well.
