add the option to set enabled or disabled default for new game menu

[kingarthur]

what im looking for is a way to without needing to remove or modify the autoplace of spawners to be able to set the checkbox in the new game gui to off by default. currently angels mods are not balanced correctly for biters to be enabled normally. we would like the ability to turn them off without actually removing the autoplace should a player wish to enable them. as far as i have found the autoplace control contains no such option and theres no where else it can be done without adding a mod startup setting to enable them for the new game gui to have the toggle work correctly.
