Fusion makes it possible for you to define the drive order for pens. This order is then used in areas where it is helpful for Fusion to direct you to the next pen when you are physically driving around the feedlot.
To change the order, just drag and drop the pens into their drive order. When you are finished, click the Save button. If you change your mind, click the Cancel button.
You can open this window by using the Change Ordering… menu button in the Pen List window. You will then choose the Change Drive Order For menu and the location you want to change the order for.
