Add Content To auth0:widget

Is it possible to add what is essentially a footer to the auth0:widget login form with the new universal login page (custom HTML) and a custom domain? I was able to use Customize Login Page within the Management console adding it below the form elements as proof of concept. However, I haven’t been able to accomplish the same once I have to include the auth0:widget pushing up through the Management API. I also would like an overall page footer similar to below.
