Is it possible? I don’t see a option 
Hello
This option not possible at this time.
Massa
Is this still not an option?! I need to duplicate probably 75+ members pages from the first one I was going to use as a template and it would definitely help me immensely. Thanks in advance 
Unfortunately, as of 2023, the option to duplicate member pages on Wix is still not available.
Please add this option. It would be helpful for working on content behind the scenes. It would also be helpful to make member pages “not visible” so you can work on them behind the scenes.
Here in 2024 same problem still not possible
Although duplicating the members page is still not an option, I found a work around by saving each section. On the right of each section the three dots will lead you to the option “saved sections”. On the new members page I add the saved section at the bottom of the insert elements. Then I only have to edit the items - not redo the whole format. Although not perfect I hope this helps a little for your project.
