Set the fields in a certain order that will not change for exports and have alias headers

For downstream systems, the headers must have specific names that are not related to how the Planners use Anaplan. Also, some of the downstream systems are very specific about the order of the fields in the export. When Anaplan has to adapt to business changes, the export to the downstream systems has to remain constant or require work by other developers and build a lot of dependencies between up to 10 teams. It would be beneficial if the export could have the ability to retain the order and have alias'ed headers for an export.
