Hi
@ChrisTrettaNot possible today. However, I have opened a Uservoice here
https://techcommunity.microsoft.com/t5/microsoft-stream-ideas/stream-tab-view-in-teams-channels/idi-...Would vote to push it up the agenda
Obviously, as Stream is transitioning to a new experience within SharePoint and OneDrive it remains to be seen if this experience of surfacing channels within Teams will continue in the future - so the uservoice may be rejected. However, where stream videos are surfaced into Teams in the new experience this should permit a list or gallery view
Hope that answers your question!
Best, Chris
