Google Tag Manager and Google Optimize

I really enjoy the Analytics feature in your plugin because it allows to disable it when administrators or editors are visiting the website. I think that it is more precise and more comfortable to set up / maintain than blocking internal IPs.

I have a pair of questions regarding Google Tag Manager and Google Optimize.

(1) If I use the add_to_aioseop_head action to insert the Google Tag Manager container, will it be placed before or after the Analyitcs script?

(2) A feature request: in the settings panel, below the Analytics tracking code field, would it be possible to add a field for the Google Optimize (A/B testing) tracking code? It should be integrated in the Analytics script, after the Analytics tracking code line and before the send pageview line.
It would be even greater if, when the Google Optimize tracking code is provided, AIO SEO could add the page-hiding snippet before the Analytics script. (it avoids flickering during testing)
