Restrict Movement in Dynamic Lighting

I understand that this is an option in Legacy Lighting, but I was wondering if there's an option to restrict tokens from moving beyond the walls I will create in Dynamic Lighting instead. Is there a function already existing for this or an API? From what I've searched, I've only seen recommendations of Fog of War, but I want players to not be able to bypass those walls in the first place. 

On the Page Settings there is a checkbox called "Movement", "Dynamic Lighting Barriers Restrict Movement" which is what you're looking for. 

why is this not in the game settings, it sucks haveing to turn this on for every single new page.
