@kcm05 Hi! If you are a subscriber you have access to custom teams. If you’re not a subscriber, you must purchase the Custom Teams Unlock to gain access to custom teams.
Click Custom Teams on the left side menu.
Click the green button to create a New Team
Fill out the form to create the team
Once created, click the Manage link for the team
This takes you to a search feature where you can add Position Players and Pitchers
Search for the players you want to add to the team using the many search criteria
When the team reaches the minimum required number of players, you can select the team during game configuration.
You can add the same player to all the Custom Teams you create.
Hope that helps,
Jeremy
