Add additional fonts to “My fonts” within Google Docs

Question

I've noticed that you can now add your own fonts to Google Docs. When clicking the More fonts... button, the following dialog box appears:

On the right hand side, the My fonts section shows some custom fonts that are installed on my Mac. When I select Avenir, the additional weights (Light, Bold, Heavy etc) are not available.

Is it possible to install the full font family without installing an extension? I can't see any additional options to add more.

Unfortunately, look's like Google Drive doesn't allow to add or use fonts that are not included in the Fonts.Google.com suite.
