Using Two Tables for Login Query

Is it possible to use the same login form that queries two different login tables?

Each table has users with different email domains, i.e., TABLE 1 has *@abc.com; TABLE 2 has *@def.net.

Is it possible for both of these user types to use the same login form and both gain access to the same site?

Is this possible with two Security Providers and Security Logins in the same Action Step?
