Item Code column visible on Contract and Invoice

There is a field "Item Code" in Prime and Subcontracts but it only sits in the background of the contract items.

We find (more commonly in Unit Price contracts) that the Item Code that you need to present to the client or subcontractor presents to you are not necessarily the same as your Job Cost Code so looking at the Schedule of Rates or when building up your Prime or Sub Invoice it would be very useful to be able to see, sort and search for this Item code.

Could the Item Code be made visible on the Contract and Invoice screens?
