BrightPearl App to support 3PL interface

I need an BrightPearl App that will create a CSV file (in set, but simply format) for a selected group of sales. The fields required are mostly very standard (delivery address, contact information, product id, quantity) but do also contain some default columns (telling the 3PL how to dispatch the shipment - these are the same for all orders). Additionally the 3Pl interface uses a continuation character to denote that this order has multiple lines. The generation of the csv file could be triggered from a set of goods out notes (for a given warehouse) or from a filtered set of Orders
