Use multiple google-services.json and GoogleService-Info.plist files in the same color

Can two google-services.json files be used in an android project? I know it is possible to use multiple google-services.json files for multiple options, but is it possible to somehow combine two files with different ones project_info

and use them at the same time for a project?

Below is an example of two files that I want to use in one project and one flavor (one for Google Analytics and another for advertising).

The first google-services.json

{
  "project_info": {
    "project_number": "XXXXXXXXXXXX",
    "project_id": "project-one"
  },
  "client": [
    (...)
  ],
  "configuration_version": "1"
}

      

        
        
        
      

    

Second google-services.json

{
  "project_info": {
    "project_number": "YYYYYYYYYYYY",
    "firebase_url": "https://project-two.firebaseio.com",
    "project_id": "project-two",
    "storage_bucket": "project-two.appspot.com"
  },
  "client": [
    (...)
  ],
  "configuration_version": "1"
}

      

        
        
        
      

    

Also I have the same question regarding files GoogleService-Info.plist

for an iOS project.
