I have multiple "season files" created with all the teams I want to use for my next sim league. Now I need to create more files so that all these teams can play each other. So lets say I have one file with nfc south and nfc east. I need to create a file of nfc south nfl north. Do I have to recreate my nfc north teams, playbooks, created players, etc..., or is there a way to transfer my nfc north from its file to my nfc south file?
