To quickly create multiple pages with similar content, create a starter page with basic content, and make a copy you can then customize. This works best if you're creating a set of pages that contain similar, but slightly varying, content.
Find the page you want to duplicate, click the three vertical dots at the right edge of the page panel (not the panel's middle) and select Duplicate Page.
The duplicated page is listed with the same name as the original, so rename it by clicking that page's vertical dots and selecting Page Settings.
Enter a new name in the Page Title field and click Done.
Click the renamed page to begin customizing its content.
