Product and Location ID Fields in API

The API documentation notes that the invoice additional charges lines and credit note additional charges lines don't include the ProductID field. Therefore, we need to link the additional charges tables to the product table using the Description field, which links to the name of the product in the Product table. However, because the name does not need to be unique, this can cause ambiguity. Would it be possible to add the ProductID field to the API?

Another issue is that Sale includes the Location string, but not the LocationID. Where a location name has changed, historic records don't appear to update with the new name, so linking the sales table to the location table no longer works. Linking using the LocationID field would ignore any name changes over time.
