Question CreateGroup() with a second schema template

I can create groups in an editor script with something like the below:

Code (CSharp):

1. group = settings.CreateGroup(campaignName, false, false, false, settings.DefaultGroup.Schemas);

I set the defaults by editing the Packed Assets file in the AssetGroupTemplates folder.
Now i am looking to create another set of defaults but i have no idea how to change the last parameter to point at my new .asset template
