I would like to have a Shared Channel Feature in a Team. We currently have people who belong to different Teams who at times may work on a project together (CENTRAL Office with Classroom Teacher) they do not belong to the same Team. I could not make a Private Channel in the Team and add the teacher. I do not want to make a bunch of Teams or have others make a Team when they may only use the Team for a project or a Teaching Unit. So I would like the ability to make a Private Channel where I can add members who are not part of the Team the channel was made in.
