Login to an external client using different connection than "Username-Password-Authentication"

Hi,
We have set up an integration with an external party via SAML, all works well and the link from the external party redirects to the Login page of Auth0. When we try to login, we see that the request to Auth0, always uses the attribute “connection” hardcoded to “Username-Password-Authentication”.

The problem is:
Our users are in different databases/connections (all managed anyways from Auth0), lets say: Germany-users.

How do I set the connection to be an parameter? Is this possible?

Thanks

Diego
