Add custom field multiple times in the same layout

I'm new to zoho and just trying to get the interface set up to start using it. I want to be able to add a new custom field to a layout with multiple instances of the same custom field. For example, we sell several products and have several ways the products can be leased or purchased. I would like multiple instances of the same pick list (product) and multiple instances of an associated pick list (purchase or lease) and a date associated with it. Is there an easy way to do this?
