Your requirement can be achieved using the custom code depending on the theme that you are using. So, if you want then I can assist you on the same. So, kindly let me know which theme you are using and your store URL too so that we can proceed further on it.
Thank you for sharing the theme name and the URL.
But as this is the paid theme so with out store access and without checking the theme/file structure I cannot suggest any solution. So,if it's possible for you to share your store access with me then kindly let me know so that I can assist you further.
