Total Inventory by SKU Report - Add SKU Cost

Currently there is no way in ShipEdge to get a historical inventory count that also includes cost. This is helpful for tax purposes, and reporting. The Total Inventory by SKU Report is the only one that I can see that lets me take a snapshot in time and see what inventory was in the warehouse. If this had cost add to it by SKU it would allow a full snapshot to be taken. Columns would be: company_name, sku, description, **cost**, available pending, processing, total, date
