Urgent request to add a 'Refresh' from sandbox to production!

Is there a staging environment for DAM? We've only been provided with Production, a test environment would be very useful in DAM.

I think you are asking for the ability to publish from a staging environment to production. I have been asking for this since we started using this tool two years ago. It is badly needed. My team wastes a lot of time recreating what we already built in sandbox/preview environments and risks missing things in the recreation. This feature would help resolve this and apply more controls over our production environment.
