While I appreciate the response, this is a terrible solution.

This is completely impractical if you are paying a large amount of bills for one vendor.

We regularly pay 30-50 bills for a single vendor with terms discounts.  Adding this up manually is a complete waste of time for something that the developers could add with a few hours of work.

This has also been a feature of Quickbooks desktop for years.  It's sad to see this basic accounting feature missing from your newer flagship product.
