Hi, is there any way, configuration or customization, to get the Add Product module in the "New Lead" section?

Normally when a lead is already created and saved, and when I go to edit it, I can see the Products and add them, add discount, tax and see the grand total. But there should be a way to get that while creating the new lead as well. How else will my sales person pitch if they can't see the products at the same time. 

Please help, this is very critical.
