I have also made a version of this that works in Excel with VBA and can archive shipment information to a second Excel Log sheet. This would make identifying data about a sample (when it shipped, what the airbill number was, etc.) easier. Let me know if you would be interested in that.
My github repo and a readme can be found HERE and you can email with any questions you might have at o n d r e y @gmail.com (without the spaces)
