Woocommerce category images

hi there,
this might be a question for the woocommerce guys – but i thought i’d ask here first.
you know how a product’s featured image is displayed as the category image for that product as well – is there any way to change this for one of the product’s other gallery images?
case in point, a tea shop uses a picture of a pot & some tea as the featured image – but they would like a close up picture of the tea (only) on the category page.


note: this is the old, live site – not the new one i’m building using enfold.
thanks,
Jason
