How do I turn episodes on and off if I turn them on accidentially?

If you are shooting multiple episodes at the same time, you can turn on Episodes as long as you are a Shot Lister Pro subscriber. Simply open the project settings and turn on Episodes. This creates a new level in the hierarchy with scenes now being inside an episode. 

And if you accidentally turn episodes on in a non-episodic project, turning episodes off in Project Settings will revert your project back to a non episode project.
