Inventory cost in sales orders

Is there any possible way in a Sales Orders inventory line to see (add a column) for the cost of the inventory?
If its not possible, any chance of adding a mark-up column like the Discount column which is already there?
Thanks in advance

This has been discussed at great length in this forum already

There is not a lot of point in creating yet another topic on the same request

This would be incorrect accounting. Cost of goods is determined at the moment of sale, not when a sales order is entered. It could easily change prior to invoicing. In fact, if the item is out of stock when the sales order is created, there would be no cost.
