Global playlists available to all subspaces

So, I've distributed 20 units across different departments in the organisation, as well as a couple of them in receptions and/or lunchrooms. Today every department is master of their unit(s). Would like some way for management to create a playlist or layout, that they can update regulary with relevant info, which is available for all departments to import into their own information rotation as they see fit. What is the best way to go about it? George said that the playlist had to be copied/cloned to the other (sub)workspaces manually by someone with access to everything, when ever the management updated their playlist in their workspace. Which isn't very user friendly. Thoughts on how best to solve this?
