You can add additional streams to existing adaptive groups.

To Add Streams to an Adaptive Group:

Select the Group to which you want to add a stream, and click button, and then Edit. The Adaptive live streams group window is displayed.
Click button for as many streams as you want to include in the group. Another Stream row will be added in the above table to which a desired Bitrate must be specified. When clicking on the red at the end of any of the stream rows, the stream will be deleted from the group.
