[Resolved] duplicating (cloning) a page?

I’m not sure what the best way to explain this is, so bear with me.

I’ve built pages on my site using GenerateBlocks, for example:

https://www.flickfilosopher.com/movies-for-the-resistance
https://www.flickfilosopher.com/on-netflix-globally

I’d like to create additional similar pages with the same layout but, obviously, different content. If I cut and paste the code and replace the live content (ie, the featured review at the top of the pages, the lists of films below), will that work?

I’m concerned because I see that the code contains stuff like this:

"uniqueId":"84d7aae8"

and I’m worried that if more than one page has this same “uniqueId” that may cause problems.

These pages were fiddly to build and I really want to be sure they’re all laid out in the same way.

If there’s some other way to duplicate a page as I need to do, that would be great to know.

Thanks for any advice.
