Select output ports that you would like to have the link from, click the input port of a transformer or a Writer, and Workbench would create links.
Usually it's too slow to go to View > Feature Type Connections and select the sources and destination, thus I'm linking the ports one by one.
It would be handy to have the functionality of linking multiple output ports to an input port straight in the UI, and not in an separate window (Feature Type Connections).
