Amending date when reversing BOM build

You should be able to amend the reversal date of the BOM build when reversing it. A date field shows up, but is greyed out and automatically populated with today's date. This causes issues when trying to do a retrospective Stock Valuation because the components of the build are counted as well as the built product. For example, a BOM Build is done on 27/02/2018, and reversed on the 01/03/2018. If you run a stock valuation dated the 28/02/2018, it'll count the built product that was created on the 27/02/2018, as well as the components that were a part of it because it's now been reversed.
