   I have a similar requirement, and I solved it by creating a "rollup view" for each table that looks something like this:
   
   ```sql
   SELECT
       'Acme' as client_name,
       *
   FROM
       schema_for_acme.my_table
   UNION ALL
   SELECT
       'Widgets, Inc.' as client_name,
       *
   FROM
       schema_for_widgets_inc.my_table
   UNION ALL
   -- etc.
   ```
   
   As a result, we can use a "master" dashboard with a filter control that staff can use, and use row-level security and RBAC to allow clients to see that same dashboard, but limit the data being returned. Client accounts are also prevented from accessing SQL Lab, etc.
   
   The view is a temporary construct—we'll have a stage in our `dbt` pipeline that outputs fully materialized "master" tables.
