Experiment Activation Mode Questions

Experiment Activation Mode Questions

Hi, I have a few questions about Experiment Activation Mode on a A/B Test. 

I'm firing the PageSense snippet over Google Tag Manager, using the tag template provided by PageSense.

I'd like to activate the test only on a few pages.

Example, I have the following pages: 

www.test.com
www.test.com/orange
www.test.com/bicycle
www.test.com/black

All of them are running the basic snippet over GTM, but I want to run the test only at /orange and /black (and other hundreds of URL's that I can easily identify at GTM, but not using URL filter)

In this case, can I configure the "URL Targeting" to "URL contains" "www.test.com", and set "Experiment Activation Mode" to "Activate manually", firing the following script over Google Tag Manager only in the pages that I want to run the experiment? 
  1. <script>
  2. window.pagesense = window.pagesense || [];
  3. window.pagesense.push(['activate']);
  4. </script>
If yes, do I need to configure it to run only after the PageSense regular script? 

I did a test on this and the QA mode still says that pages where I'm not firing this script are running the experiment. 

Thanks.
