Changing Costing Method

Customer is live only on Navision Sales & Receivables - mostly for practice purposes. They enter orders and invoice them. Not using inventory quantities or GL yet (going to start in a month or so). They did though entered many item cards already. They did not receive any inventory yet (all costs are still zero).

Some items have been entered as FIFO or Standard by mistake. What’s the easiest way to change it to Average? Since there are Ledger Entries the system will not allow to change the costing method.
