Often a customer will place an order for multiple lines.  The sales order is entered and then SO-N is used to create work orders.  Sometimes a customer will come back and modify a PO changing dates, prices, quantities.
 
After modifying the sales order, an option to re-run SO-N on the existing work orders to incorporate all of the changes would be awesome.  As it is now the changes must be made in the sales order and then each individual work orders needs to be changed one at a time.
 
An option to change a bom and then apply the changes to all open but not issued work orders for the part would also be a huge time saver.
