Can i use for each product a different item of a content type ?

Hi:
I'm doing a web site where I need to sell diferents Templates. I wanna associate a specific product with a specific template. That means i buy a product thus i'm buying a template that needs more information to be saved.
How can i configurate that ?
I was trying in admin/store/settings/node-checkout but it associates all the products with a particular Template. I wanna for each product one template.
Can you help me ?.
Thank you.

Manuel.
