I use the business functions in GnuCash, and regularly need to export customer account data to use in other applications. Currently, the easiest way to do this seems to be by using the customer/Vendor Listing, Customer/Vendor Summary, and Receivables/payables aging reports, but there is no way to include the customer or vendor numbers, which are a much more robust key field than the customer name.

Is it possible to include the number field in these reports?
