The SharePoint List Column allows you to map radio buttons to SharePoint list elements by pulling in the option lists from your SharePoint integration.
The benefit of adding a list is that it can be added to any form. If the list needs to be changed, that change only needs to be made once, and the forms will automatically update to use the new list.
