In AutoCAD MEP 2009, we made some changes to how electrical panel schedules are created. In prior releases, the panel schedules were generated by VBA code and were difficult to customize. They are now based on AutoCAD tables and users can create their own schedule "templates" to match their company standards. You can even bring in an existing Microsoft Excel schedule to speed up the creation process.
We have published a white paper which explains in more detail how to create your own custom panel schedules. Link to whitepaper: AutoCAD MEP Panel Schedule Whitepaper
