Using Entity Widget
The Entity widget links to data that has been loaded into indexes for matching.
The Entity widget  is similar to the Dataset widget used in other pipelines, except that instead of
            reading data from a table it links to data that has been loaded into indexes for
            matching. The Entity widget allows you to specify the entity name and displays
            the associated columns that are available. You can also specify if the entity is the
            source or target for the matching. All screening pipelines must specify a single source
            and target.
