Ember-CLI - Is there a way to have a separate file for my ember-cli app config compiled javascript after build?

I'm currently using storeConfigInMeta: false flag in Brocfile.js to have my application configuration 'config/environment' in compiled javascript files instead of meta tag and now I need to have it in a separate file after building my application to be able to change my configuration without making new ember-cli build. 1) Can anyone help me with that ? 2) If (1) is not doable. Is there a way to have a separate file with only the properties I need it to be configurable and somehow link it to my 'config/environment' module ?
