When inserting schedules on the drawing, you can group headings into subheadings by adding a column group label followed by the | character (Shift+\).

For example, the image below shows a feeder schedule with the default labels for the columns:

To edit the column headings, after running the command for your schedule, press the Edit Title, Column Labels, and Column Order button. You can also run the label group command for the schedule.

Ribbon: DM: Customization->Project Customization-> (Desired Schedule) Label Group

Pulldown Menu: DM->Customization->Labels and Schedules->Project List->Edit (Desired Schedule) Project List

To group the column headings for conductor wires and neutral wires, make the changes shown in the image below:

Notice the conductor labels are next to each other and both begin with “CONDUCTOR|”. The neutral labels are also next to each other and both begin with “NEUTRAL|”. The labels must be adjacent and begin with the same name to be grouped.

After you save your changes and update the schedule, the columns will look like this:
