We have DQ+ 3.3, fixpack 3 running in an on-premise/enterprise deployment.
In the Details tab of the Environment administration page, towards the bottom under the "Manage Super Groups" button is a section titled "Security:"

What does moving a Super Group from the "Available Super Groups" to the "Selected Super Groups" list do within the environment? I can't find any mention of this configuration setting in the documentation, but maybe I'm not looking in the right places.
I always assumed that you had to move a Super Group into the "Selected Super Groups" list before it would be available for use in the environment. But that's not the case. I tested this and I can assign pipeline permissions from groups in the "Available" as well as the "Selected" list. Super Groups are specific to the environment in which they are defined, so I'm not sure why you would need to further "Select" them.
In short, when would I ever want to move groups from "Available" to "Selected" within this part of the configuration dialog?
