MDM Last Login History table?

Hello,

I was wondering if anyone was aware if the last date/time login history of a mdm user to a repository is actually stored in one of the DBMS tables for a repository schema. We are aware of the Audit xml log file that tracks actions of when a user logs into a repository - but we are trying to find out if this is already recored in one of the MDM database tables so we can more easily make use of last login time for custom development.

Thanks.
