I'm sorry that I don't have an answer to this but I wanted to add a comment.
This seems like such a basic function that...
- I'm surprised you can't copy a page without it being linked to the original
- Unable to create a template for frequently used page styles
- That any of this functionality (or lack thereof) isn't being called out in their documentation.
Its one thing to not include something as basic as page copy/template creation in the app, but then not to address it in documentation so the user starts to question their own sanity (which I have as well) is just... crazy.
Every single person who uses this app is going to have this very question. Why not just address it by saying you can't do it so we don't spend hours looking at videos and reading countless web pages to no avail because surely... there is a copy function... !?
