Exclude refunded items from Analytics -> Products report

I placed two orders for a test product that I created, paid for them, and then refunded them.

The report still includes them as “Sales” under Analytics -> Products.

When I go to Analytics -> Settings, it lets me choose “Excluded Statuses” for the report, but it says “Orders with these statuses are excluded from the totals in your reports. The Refunded status can not be excluded.”

Not being able to exclude refunded orders makes the reports totally useless for my clients, who need to know how many products ACTUALLY SOLD and were paid for.

Please give us the option to excluded refunded products.
