Products Price Manager

I am using the products price manager for the first time on a clients site and have it working great...love it!

But they have 271 products I need to have the pricing copied to.....all the products are the exact same price discount structure...but I have noticed there is no easy way to do this in the admin?

Can anyone more savvy than me offer a way I can copy the product pricing discount I have created for one product to an entire category and all its subcategories?

I am imagining this will be an SQL thing but I am clueless where to start...

I just cannot begin to think of the torture of doing this by hand with 271 products.....so any help is GREATLY appreciated!!!

Are you saying that you are trying to set up something like:

Qty Discount
3 10
6 20
9 30

on all of the products?
