I recently modeled a project involving residential units, where the electrical load is based on watts per sq. ft. and the kitchen has fixed number of required circuits. In order to use the Revit panel schedule feature, I copied the default receptacle and named it 'Dwell..." with an assigned load of 0-VA. Than I had specific outlets, common to each residential unit, where I assigned the VA for the kitchen receptacle circuit (for example). I could still circuit all of the receptacles I needed but avoided having a runaway VA (based on qty x 180VA). This doen's answer your question, but it might suggest a work around.
With regards to exporting Revit Panel Schedules, this cannot be done without third party software.
