Players trade in season mode

Is there any way to stop automatical players assigning to the teams? I play season and I have 10 or 12 players in team and I want to remain the same players in teams after simulation. In trade, etc. settings I put everything OFF but after simulating games every team assigns random players. How to disable this? Or at least how to edit CPU team rotation? Thanks.

You have to have at least 14 players on every team. You could create 3 fake players that are injured for the entire season and assign them to a team but I think the hardship exception will all cpu to pick up more players
