Update costing and estimated profit on outstanding sales orders

For example I create a SOP and the cost and estimated profit for that order are calculated based on current prices, it may be weeks or months before this SOP is despatched in which time those cost estimates could have changed several times but sage will still show the original. This is particularly true with BOM items. Removing and re-adding sop lines works for one or two items but isn't practical on any scale. A routine to update costing on some or all outstanding SOP and recalculate the estimated profit would help to keep better track of profit margins on existing incomplete orders.
