Report sales with tax break-up

Report sales with tax break-up

Hello - I'm trying to generate a sales report with a break up of the sales amount as well as the corresponding VAT. However the sales report includes the tax amount as well. This seems like a very basic sales figure. I can get the figure in the TAX report, but there are some sales which don't have tax (like exports and services) so this wont work for me either.

Am I missing something or this is a glaring omission in the product?
