I have a motorcycle parts store. I currently have up to eight product entries for the same product. The only diffence is part number based on what year it fits. I'd like to streamline this and have one product entry with multiple "Add to cart based on year and part number. What do I need to do to accomplish this? Is it an add-on or is Zen capable of this out-of-the-box?

I apologize if this has been answered before. I tried search but didn't know the correct terminology. I am a novice and learning on the fly. I am currenly using 1.3.8b, haven't figured out how to upgrade without loseing all my mods. Glad I backed eveything up before.

Thank you in advance.

Eddie
