Ability to hide the Owners column from the Dashboard Gallery to Dashboard Viewers

What is the problem or goal the end user is trying to solve or accomplish?

They want to share a Dashboard with only a sub-set of their Dashboard Viewers, and therefore the Dashboard is on Draft status and all the users that need access to it are added as Owners.

However, the users currently can see the list of Owners from the Dashboard Gallery, which is not ideal to their use-case.

How are they solving it currently?

The only workaround is to create one Dashboard for each user, so that they don't see each other on the Owners list.

What is the recommended solution by the Customer?

Provide the ability to hide the Owners column for the Dashboard Viewers.
