Config file locations and how to set them for testing

Development Programming & Scripting C++

So I have this: UCLASS(config=SomeCustomConfigFile) and it creates a file in D:\Projects\ProjectName\Intermediate\Config\CoalescedSourceConfigs\SomeCustomConfigFile.ini

But this keeps getting reset, how do I use and test custom ini files? I was expecting it to be in D:\Projects\ProjectName\Saved\Config and to only need to be setup with defaults once.
