So I'd need to add a field in admin(new product page) that would display in the product listing and which could be used as a basis in the listing's sort dropdown..

Basically i'd just need to copy product attribute "model" and rename it to location..

I might be able to copy and rename things called model with developer tool kit but I'm afraid I need to know some database stuff and to be honest I don't... So once again I'm calling the help of zen gods..

many thanks!
