If there isn’t one try Cheat Engine. You can learn how to use it quite fast; it is a simple and easy tool to use. Or you could try to find a savegame editor.

Games are added to the WeMod library automatically once WeMod detects that enough community members have the game.

When (if) that happens, you’ll need to add the game to your WeMod favourites so the trainer developers can determine how popular the game is in the community and place it in the queue accordingly.

See here for more information on how trainers are made and updated: Game Queue - WeMod Support.
