A project has 24 branch panel schedules that all need the same formatting changes.

To ensure consistency and efficiency when multiple branch panel schedules require identical formatting, Revit allows applying a panel schedule template to one or more schedules simultaneously.

The documented procedure states:

“You can apply a template to one or more existing panel schedules.”

And further:

“Select the panel schedule(s).

For Apply Templates, specify the template to apply to the selected panel.”

This functionality lets an electrical designer select all 24 branch panel schedules in the Project Browser, right‑click and apply the desired template to update formatting across all selected schedules in a single operation.
