Exporting Invoices with additional_meta_data

I am looking to export all invoices AND include all the ‘additional_meta_data‘ as the meta data includes several custom fields which are required for tax reporting.

Is this possible via a plugin or would it require an enhancement to the export script to accomplish this? When I view an individual invoice, I see all the data, but not via export.
