You can create an override view of your listing view (div, list or table) in your Main HikaShop Configuration, go to Display dropdown and select Views.
Use the three dropdowns filter to find concerned views with Product/ Your Template/ Front end, and depends from your Item Menu configuration select listing_div, listing_list or listing_table.
That operation will required html & php knowledge, for methodology see

to understand displaying view process, you can too switch the Display view files option to Front-end (in Main HikaShop Configuration and Advanced tab).
Hope you will succeed in what you want achieved.
