Hi @anarchoi,
It’s possible, yes, but for this you’d need some custom PHP/MySQL coding. It’s not something the plugin can do out of the box.
If you’re not a developer (or if you don’t have the time and/or skills to do it yourself) you’ll want to find someone who can help you with this.
I’m a PHP developer, I looked at your template but it’s a JSON file. So I can’t add PHP conditional statements in a JSON file. Which file should I put my IF has_post_thumbnail() code in?
You should look either into the existing filter hooks and see if you can use any of them to achieve your goal, or directly interact with the Query class (and the filter hooks it has) to customize the query so it return only posts that have featured images assigned to them.
