Unable to extend multiple build profiles

[dannyBies]

Summary

I am trying to enable Maestro E2E tests in my project. I have to run my tests in multiple different environments and thus would like to reuse common shared config like this:

"e2e": {
      "withoutCredentials": true,
      "config": "build-and-maestro-test.yml",
      "android": {
        "buildType": "apk",
        "image": "latest"
      },
      "ios": {
        "simulator": true,
        "image": "latest"
      }
    },

I would then like to use this base profile together with my environment specific profile. This is currently not possible as I'm not able to pass in an array of profiles to extend from. I'd like to be able to pass in an array of profiles in which the last specified profile takes precedence in case the same config gets used in multiple profiles.
This is needed as I need access to the profile specific env variables + the e2e config but I don't want to redefine my env variables as this makes it easy to accidentally make a mistake.

Example code of what I would like:

"e2e": {
      "withoutCredentials": true,
      "config": "build-and-maestro-test.yml",
      "android": {
        "buildType": "apk",
        "image": "latest"
      },
      "ios": {
        "simulator": true,
        "image": "latest"
      }
    },
"qa": {
      "distribution": "internal",
      "autoIncrement": true,
      "env": {
        "EXPO_PUBLIC_APP_VARIANT": "qa",
        "EXPO_PUBLIC_API_URL": "...",
        "...": "...",
      }
    },
"qa:e2e: {
      "extends": ["qa", "e2e"]
}

As I need to manage many different profiles this would make it much easier to reuse different profiles and reduce the chance of making mistakes.

Managed or bare?
