Uploading Videos In Microsoft Stream

Sorry I'm not following the question or your table.

Stream supports organizing videos as follows...

1.  by themselves as single files (no organization)
2. into company wide channels (company wide channels have no sub- organization under them)
3. into a group (tied to an O365 group)
4. into a channel inside a group (2nd level organization under a group)

We don't have any other organization methods. No other ways to have multiple levels of hierarchy. No other way to group videos into playlists, etc.

Only other way you can loosly tie videos together is with a #hastag. Clicking the #hashtag will search for other videos with the same #hastag.
