Angular – Build to Output path based off environment

I am trying to figure out how to build and deploy an Angular 2 project built with angular cli based off of variables in my environment typescript files.

For example, my angular-cli.json file has a dev environment declared that points to "environments/environment.dev.ts". This file has the following properties:

export const environment = {
  production: false,
  'output-path': '\\\\testServer\\apps\\appName\\'
};

What I would like to do is be able to call ng build –dev, and the cli would build the app with the dev file (which it does correctly), but also output it to the output-path, which in this case would be a network share. Is there anyway to do this without incorporating some other CI tool and/or gulp?

I have manually added the -o (–output-path) option when building and passed the path, but I don't want to build a solution for the company that would require developers to manually type paths each time.

I am aware I could update the package.json to add new commands for build/deploy with the –output-path parameter, but that would require updating the paths in multiple files and adding lots of new commands (ones for local, dev, test, prod).

Does anyone have a good solution for this?
