PowerCMS does not physically create another page, but with the use of the templates feature in PowerCMS you can use the same page to load different content based on a Query String.
To do this, in PowerCMS create a content location and make sure to check the check box to make it a template. then create all the regions you want for that Template. Then next to that template in the left column there should be a + button which allow you to add pages off that template. Once you have all the pages, you can then copy the Developer notes to your page and update the links to have the Additional parameter that is specified in the Developer notes of the template pages.
