Automatic Linking on a Per-Site Basis in Multi-site

We have a network of about 70 sites we're using Infinite SEO's Automatic Linking feature. I can see where we can control the links from the Network side on the settings page, but is there a way to override this on a per-site basis?

On the bottom of the settings screen it says "Allow Site Admin access - If enabled, this tab will be available to Site Admins once you switch to per-blog mode." --- Where can Site Admins see this tab? How do you switch to "per-blog" mode?

Thanks
