Multiple Entreprise Connection in one button


I’m using the new Universal login form with some social connections, database connection and multiple Azure AD Connection.
One of the social connection is Microsoft Account Social connection, so many user try to connect with Microsoft account while their email are only registered in the AD Connection.
I know we can add the Azure AD Connection as a option like social connection, but I have many of them and an authentication page with a button for each different AD connection is not an option.
Is there an option to have all Azure AD Connection in a single button, or can we customize the form to make that possible.
Also I know that identifier first would work but it’s too confusing for users.

I would like to make it look like that
Feel free to make any proposal that can help me on that :grinning:
