This feature was available in Office 365 Video. We were able to create a channel and assign specific users to manage that channel (create content, etc). It also allowed those channels to be viewed by everyone in our organization. Unfortunately, that option isn't available in Stream and it was a big feature we used as a school district. In Stream, you only could have a private or companywide channel. In private, no one sees it. In compandwide, everyone see it but you have to grant specific users 'content creators' to be able to upload to that channel. The issue with that; when you grant a user 'content creators' they can upload anywhere. We need to be able to only allow them to upload to their specific channel; all while letting everyone view it. Please help and bump this up and get this on the road map.
