Trouble with application id and custom nativescript.config.ts

I have this project.json setup where the nativescript.config-aaa.ts contains a different appResourcesPath than the default (nativescript.config.ts). This seems to work fine.

However, I'm also building for different environments, and have to set the application id based on that, so I add "id" to the config.

        "app-test": {
          "flags": "--config=nativescript.config-aaa.ts",
          "id": "com.app.aaa.test"
...
        "app-dev": {
          "flags": "--config=nativescript.config-aaa.ts",
          "id": "com.app.aaa.dev"

The problem is that the id replacements happens in the default nativescript.config.ts, while the rest of the build process is using the specified nativescript.config-aaa.ts.

Any tips on how I can handle this situation properly?

Start with project.json and compare how --config=nativescript.config-aaa.ts is used with how the application id is replaced in nativescript.config.ts. Reproduce the app-test and app-dev builds, then verify that the selected custom configuration receives the corresponding id while retaining its appResourcesPath.
