Is it possible to transfer my custom plays between leagues?

I have about 150 custom plays. I created a new league to test some teambuilding strategies. How do I transfer my plays to the new league?

Thank you.

I don't think you can transfer playbooks and custom plays between leagues. I had the same issue myself and found on these boards they cannot be transfered.

Well you can transfer customized playbooks by exporting and importing. However, you can't transfer the plays that go with them, as far as I can tell. I know they are starting a new 2022 game... I hope they've upgraded this for the new version.
