Request: A mode for import/export that ignores whether the value of an existing key or feature flag is different, aka, create-only or net-new mode

I'm attempting to create a process in which my pipeline automatically adds new feature flags and configurations that are introduced to the repo's appsettings.json before a deployment occurs, but I do not want to have it overwrite/flip feature flags or configuration values if they differ from what is in code. I understand that this process is not pure configuration-as-code, but it's a scenario I am sure many would like to achieve as a sort of hybrid method.

In addition, it would be nice if the Compare panel would allow you to transfer configuration settings from one App Configuration resource to another.

Without these tools, I'm left basically manually examining the appsettings.json and adding the keys by hand - something I was hoping I could automate with App Configuration. I am sure I could achieve what I want with a long enough Powershell script, but it'd just be nice to have as a built-in option.
