ATTENTiON GARY OR SOMEBODY! HOW DO I USE CUSTOM JERSEYS?

How do you use custom jerseys? These are the jerseys that appear on the player models within the game.
I created a custom 260 x 190 .png jersey with the team name, and placed it in the "C:\Wolverine Studios\DDSPB2021\app\disk\graphics\players\jerseys" folder. However, the jersey does not appear on the player model and defaults to the FA jersey. How do I map to my custom created jersey to use in-game?
Thanks in advance!
