Export excels of sales orders, fulfilments and invoices

As a wholesale business So many of our customers want copies of their orders as excels, but they want those excels to include the product barcode as well.

we have a growing number of customers asking for this and its so much extra manual work because you have no ability to do this built into the software.

Can the barcode field be added to the exports of orders in sales orders, simple and advnaced orders.

Secondly can we have the ability to export more then just the original sales order, as this is not helpful in so many cases. Customers want a copy of what we have just sent them, as we allow backorders, so  getting a list of 50 products from the original sales order, when we have only sent 10 on the current invoice, isn't helpful., they want the info to match their invoice. Can we have the ability to export them on a per fulfilment basis/ per invoice and include the barcode numbers in the export to excel etc.
