Is there a way to globally make all SA apps optimized (or not)?

This question would be unclear without additional context, but since you just posted this, I'm guessing you're still asking about this setting in Simple Automation Rules:

That answer is no. This is a setting you will have to turn in in each individual app. The "gear" page you're referring to is the app status page, which is a (view-only) summary of that particular app's internal data, most of which is the value for settings you set inside the app itself.
