View all sub-workspace's media at once under parent workspace

It would be great to be able to recursively show all the sub-workspace content in the parent workspace's media folder? Perhaps a check box in the managing workspaces area so we have the option to turn this ability on or off? This way each department can sumbit their content for review without having access to other people's work but it also saves our review committee time from having to individually click through each department (as we have many) and removes the human error of accidentally missing one. Kind of like how All Workspaces shows everything under it, except we can't use All Workspaces since we have other branches we don't want to mix in as it becomes too much content to sort through altogether.
