The "Reports" is lacking a basic feature, one should be able to separate multiple items within the same order in different lines, not having them in the same column separated by comas.
If you have an order X that has 2 items of product A and 2 item of product B, one you create the report, for order X will show Quantity 3 but you don't know how many of product A and how many of product B.
Thank you.
