Feature Request - Weight Validation

We sell food products that have a packaged weight. We would like to have a validation that takes the expected weight of all items and compares that against the actual shipment weight. We have had orders where an item was missed and it was obvious when the customer contacted us that they were inadvertently omitted based on the shipping weight. Is there a way to have the actual weight compared against the standard weight for all matched items, and if the difference deviates by +/- X ounces, then a notification is triggered
