Can symbols assign netnames?

  1. Select some pins.
  2. Right click and choose: Pin Helpers / Net Label from the popup menu.

After that, you can pull the labels away from the symbol to drag out wires from the symbol. Also experiment with mirror (x or y keys) on the labels and m for move if you don’t want the labels on the ends of the wires.

Or you start from the other side. If you have a defined alias list for your bus, you can use the Unfold from Bus function.
