INVOICES NEED TO BE ABLE TO HAVE THE OPTION TO BE SAVED AS A CSV

Our B2B customers require their invoices to be supplied as a CSV for entering into their inventory systems, however only PDF's are available at this time. The Export Sales Order details, is quite lacking, not giving the opportunity to save a default set of items to download. 

Please please can there be an option to save as CSV as well as PDF fro within CIN7?

It would also be great if orders placed in the B2B portal could be saved as a CSV too
