Feature request: organization- agnostic search in multiview

[pettycrimes420]

The idea is to have an option to add livestream to multiviews without having to specify the organization. This is going to useful when setting up multiviews for cross-company collabs with multiple POVs. Right now this can be done by either manually adding every URL or pressing the add live button, selecting "Show All", selecting an org and then adding the stream. This can have the same UI as adding URL but instead would display streams/videos that satisfy the search terms the same way search from homepage works
