We have fairly large Tableau Server instance (6,000 users and growing). Frequent user onboarding requests need to be approved by a Site Owner (we differentiate Site Owner from Site Admin). For automated self-serve onboarding requests it would be great if we can store Site Owner (and site owner backup) in Postgres Metadata, so the approval requests can be automatically routed to the appropriate Site Owner for approval. This also could be helpful in managing internal chargeback for the service. Would it be possible to add this in? Thanks. Boris.
