If you've been added as an owner to the custom column of Search Ads 360, across what account levels can you access and manage those columns?

As an owner of a custom column in Search Ads 360, you have comprehensive access and management rights across all account levels. This means you can view, edit, and utilize that custom column from the manager account down to individual client accounts and sub-manager accounts. This broad access ensures consistency and efficient data management across your entire Search Ads 360 hierarchy. The other options are incorrect because they suggest limited access (only at the manager level, sub-manager level, or client accounts), which contradicts the full ownership privileges granted for custom columns.
