Additional Fields At Product Level

We would like to see some strategically located fields added to the product level, that can be searchable at the Orders List and used for other things like workflows & Integrations. Not looking to Bloat the database just looking for a few fields that could be used for things like product Classification, Sales Tax Classification, Workflow ID. Even if one or two could be used to sort at the Order List View it could help use the Orders list for a basic schedule in production using a product classification.
