Once in edit mode:
- Select the sidebar panel
- Select the catalog
- Edit a schedule panel
From here you have 2 options: Manual vs. Channels
You will need to manually select the start and end time for your streams, in addition to location, extra information, and references. You can add as many events as you'd like.
Once you have content scheduled, you can directly pull in each feed, from each channel. Feel free to add as many channel's schedule to the sidebar.
Once you're done, save and publish your content.
