Automatic updating of price levels

I'm looking for a way to have price levels get updated automatically once a day. Let's say we use price level A for employee pricing and we want that to be set to Cost + 10% for certain departments. I know I can use an Inventory Wizard to set the prices and then send a worksheet to the stores but that's a pain to do every day. Does anybody know of a way to automate the process?

Thanks,

Ben
