We added a new way to insert feeder IDs.
The old way still works and you can continue to use it. The commands are intentionally buried a little bit to discourage their use, but they are still there. On the ribbon, if you select the One-Line Diagram label below the icons, more commands will drop down. The old feeder ID commands are located there.
The new way is to set the Insert feeder IDs inside feeder lines option to Yes. On existing projects, it will initially be set to No so that duplicate IDs are not inserted. You can change the value to Yes to use it on an existing project. On new projects, it will be set to Yes so that the new way of inserting feeder IDs is used.
When this option is set to Yes, a feeder ID is inserted in each feeder. You can move the ID along the feeder, but it cannot be moved off or removed. You can be confident that each feeder is correctly labeled with its size.
