In the pricebook report how to get the surcharge modifier amount added to list_price?

We have a price book report in which we are adding up the surcharge manually and sending it out to the customers. we produce the price book by passing the customer number and now the requirement is to automate this by getting the eligible modifier and adding the surcharge to the list_price before sending it to the customer.I understand we have to call the pricing engine to simulate which modifer is picked etc but no clue on how to do that.

Appreciate it if anyone can point me in the right direction.

Thanks
