I don’t think it’s a new feature but it would certainly be very useful - if the selected section could then be copied or cut.
Similar requests were made long ago - for example those below. I think old requests get overlooked although they’re still valid. Perhaps this one would be difficult to implement. Eg:
Copy Elements to Another Page (from 2018)
Copy/Paste in App Structure… (2019)
Copy/Paste in Design View (2019)
