Hi @MoonMoritz ,
Thanks for the feedback, we recently released a new feature to manage remote-config (and other Unity Gaming Services) as files within your project: Remote-Config Authoring tool from the Editor - Officially Released!
In the case of remote-config it allows you to organize them in multiple files in the logical way that suits you in a json format that is easier to merge. If you are interested, please try it out with the com.unity.services.deployment package. Don’t hesitate to share feedback!
