To organize your project visually, it often helps to create an alias to provide a clear connective reference (a “jump”) in the signal flow in the schematic. An Alias consists of a pair of alias input and alias output blocks. Using alias blocks can reduce the visual clutter in the schematic window created by long wire connections.
To create an alias, press the ctrl key and right-click on a block's output/input pin and the pins would get created as shown in the image below.
