Use Single Auth0 app to connect to more than 1 SFDC

Is it possible to set up 2 connections to 2 different SFDC Org’s?
Currently within the UI it seems you can only connect to 1 using SFDC supplied Client ID and secret.

As you mentioned, at this time, there’s only formal support for a single instance of each social authentication provider listed in the Dashboard. Technically, there’s support for more than one custom OAuth2 connection so given SFDC presents an OAuth2 API you could technically represent that as multiple custom OAuth2 connections, however, this requires some coding.
