Switchboard has you covered if you ever need to add existing destinations to a Stream group.
What are existing destinations?
Existing destinations are the destinations that you've previously added to your Switchboard account. Switchboard automatically saves the destination to your account whenever you add a social channel or RTMP destination and authorize it. All the saved destinations appear on the Destination Manager page, which provides an overview of all the destinations saved to your Switchboard account.
How To Add an Existing Destination to a Stream Group
Step 1
Click "ADD DESTINATIONS" at the bottom of the destination group.
Step 2
A new window will appear, opening the menu of all the available social channels you can add to the Stream Group.
You can use the search or sort feature to narrow down and find the destination you want to add to the group.
Step 4
Select the destination (s) you want to add by clicking the toggle box next to them.
Step 5
Click Done.
The Destinations are successfully added to the Stream Group.
The Destination I Want to Add Doesn't Appear on the List.
If the destination you want to add doesn't appear in the list, double-check the destination manager to make sure it hasn't been accidentally deleted.
If you don't see the destination, try adding it as a new destination by following these steps: click the 'Connect More' button and select it from the list of platforms.
