Multiple app defintions in the angular-cli.json "apps" : [ ] property

Multiple app definitions

I noticed that inside the angular-cli.json file, the "apps": property is defined as an array. Is the following a valid example of the intended use for this property?

angular-cli.json :

{
  "project": {
    "version": "1.0.0-beta.26",
    "name": "example1"
  },
  "apps": [
    {
      "root": "src",
      "outDir": "dist",
      ...
    }, 
    {
      "root": "src2",
      "outDir": "dist2",
      ...
    }
  ],
  ...
}

I’ve tested with multiple definitions in the “apps”: property. And ng build always builds the first app defintiion.

If all these assumptions are correct, How do you use ng build to compile the second app definition?

Current Config.

angular-cli: 1.0.0-beta.26 node: 6.5.0 os: win32 x64 @angular/common: 2.4.4 @angular/compiler: 2.4.4 @angular/core: 2.4.4 @angular/forms: 2.4.4 @angular/http: 2.4.4 @angular/platform-browser: 2.4.4 @angular/platform-browser-dynamic: 2.4.4 @angular/router: 3.4.4 @angular/compiler-cli: 2.4.4

Is there a timeline for this? Could you suggest a workaround until then?

That is the intended future use. However, only one app is currently supported.
