This is quite easy to do by yourself.
Copy all the code in single-tss-seasons.php.
Create a new file in your themes-folder and paste the code in there and name the template like you want it. Then replace $post->ID with season id that you want to request.
Example code for to show season matches from season id 3. Save that and set it to page template in some of your pages.
