Force a scenario to use a certain map generator definition

[twoski]

So basically i have a new scenario, and i want to force that scenario to use a specific map generator definition i made without overriding the default map generator.

This way, the player can start a game with my scenario and it generates a custom map, and they can start a game on normal with cassandra and it generates a vanilla map. The player does not need to disable my mod to stop it from overriding the vanilla map generator.

Is this possible or should i request this?

basically, i want to know why the map generators even have a defName if the default map generator is the only one ever used
