Is there a way to install node_modules globally when creating ember app using ember-cli?

Every time I generate a new ember app using the ember-cli

ember new my-app

It will have 177MB node_modules inside my-app folder. Is there a way to just install this node_modules globally and not have it on every ember project?

Note: I see you can pass --skip-npm, but how do I install the node_modules globally when I skip npm?
