Hello Sophie!

Please open a new seperate post for each question next time you need help!

Well, what you can do is create your page with that object in Step 3 - Page creation then go into Step 2 - Sitemap Creation and duplicate your page as many times as you need it.
You will then have the chance to have identical pages with the same object in them by starting from that page each time you need to build a new one, not by a blank one.
Hope this helps!
