[Support request] Looking for a Single Category Display for Terms

I just recently discovered this plugin, and have been very pleased with it’s capabilities so far!

There is a small issue that has been frustrating me, and so I’m reaching out for help. Is there a way to display a single category or tag for a post? I am creating a sports blog, but only want to display the top level sports category for each post, and not the sublevel categories. I would also be fine with displaying a single tag instead of category if that is easier. I would like to do this without having the list’s taxonomy set to a specific category or tag so that all posts can be displayed.

Thanks for any help on this issue!
