Has anyone set up a Formula in Advanced Pricing to surcharge items with Standard Cost?

I am trying to determine if there is a better way to do setups for intercompany (OU to OU) sales and instead of creating a new Price List by adding items from Inventory using the Set List Price Equal to Cost From check box every 3 quarters, I'd like to have one Price List Line for All Items/All with starting Value of zero but use a Modifier to Surcharge by adding the Standard Cost to the Zero List price automatically.  This, I assume, would require a Formula to do the lookup of the Standard Cost on the inventory item.
Has anyone ever done this before?  I am looking to avoid having to maintain this price list by regenerating a new one every 3 months for the Standard Cost.  Susan Dymerski
