Hi,
The product listing template is configured by the menu or the module.
So it will highly depends on how you display your products in your website.
But even if there is no feature for that in HikaShop ; you can use the view override of "product / listing" in order to change manually the listing template depending the current displayed category.
You should also add some checks for the menuid/moduleid in order to not affect the listing everywhere but just for the element you want to override ; otherwise it could affect a lot of listing (modules)
