Serialized items price updated

To update serialized items prices, requires to update the "Retail price" the go to"Manage Serialized Inventory" and manually update the price of each device in stock, when you have to do that to 134 items or more and some of them has in stock 6 items it takes over two hour to get it done, and I need to do this 3 times per year. The price for each item in stock should be automatically updated when you update the "Retail Price", that simple.
