Change Ratings Scale on existing dynasty?

[KingNeb]

Excited for the new adjusted scale rating. Is there a way to modify an existing dynasty to have this new rating? Or does it require a restart?

I'm thinking a restart because I don't see an option to change it. Thank you!

It will require restarting

This change is so awesome that I restarted. Thank you Gary!
