I want to do the same thing. I just loaded 7,000 products with easy populate and dread going into each one for MSRP price. If you go to the easy populate thread I asked the same question.

Here is the answer I received.
I am unfamiliar with the Dual Pricing Mod. If this mod directly changes the products database, then you can easily change Easy Populate the handle this added field. I am unfortunately (or should that be fortunately?!) involved in a large print project and 2 full eCommerce projects, so I don't have time to do this for you :(
But, this is what you need to do. If the Mod had an SQL patch, take a look at it. Did it update the products database? If so, what fields did it add? Open up easypopulate.php, and search on v_products_price. At each line reference (doing a search), add your new field, say "v_products_price_w"
Also note that the new CSV version is not quite the same as the TAB delimited version.
Wish I had time to help more, but just too busy... But this is not hard to do. Just make sure you BACKUP your databases first!

I am not good at looking at code and trying to figure out. If you are --- help would be greatly appreciated. I do not know the code where to put it. If I am not mistaken...I am using the tab delimited version.
