I want to be able to report on sales using Woocommerce based on:

• what has been despatched in a given time period (the native reporting in Woocommerce reports on sales based on when orders were placed, rather than when they are despatched);
• ideally, I also want to break down those sales (based on what has been despatched) in groupings of countries (for a UK-based retailer, we ideally want UK, EU, and Rest Of The World)

I don’t believe the native reporting in Woocommerce allows this, though I have read the docs at Woocommerce.
