Can SSO Connection user_id format be changed

For database connections, we are able to create a unique user_id. We would like to review doing the same for SSO logins via ADFS, SAML, GOOG, etc.

Currently our SSO connections will have an Auth0 user_id in the following format: “<AUTH0_STRATEGY>|<CONNECTION_NAME>|<USER.NAME>”

We wish to be in charge of the naming conventions used for user_id in Auth0, if that is possible.

I understand we could leverage app_metadata or another searchable custom field, but we specifically need to be able to query grants based on the user_id and would prefer to tweaking the existing naming convention as opposed to adding new code leveraging a custom metadata field, if possible.
