Providing Data Driven Subscription Data via a Table

Is there a generally accepted SQL Server Table where we can provide the Step 4 entities of a SSRS Subscription for a data-driven subscription? Like providing the values for To, Cc, Bcc, Reply-To, etc.. Provide those values and reference them in the Step 4 from a query provided in Step 3.

Thanks for your review and hoping I am clear enough on this and hoping for a reply.

Thanks!
