Moving a portfolio sub-page (v7.1)

Site URL: https://www.jennwright.net/

I just read here that it is not possible to move portfolio sub-pages which is really unfortunate! 

I created this portfolio page, and built out my first sub-page. After working on the sub-page, I decided the squarespace options for the portfolio main page weren't what I wanted for my site and created this one on my own...only to learn that I cannot move the sub-page I created.

Does anyone know a work around/hack that will help me move my sub-page and/or the content without recreating it from scratch? 

The links are embedded above, but posting them below for ease and clarity: 

#1-The portfolio page I created initially (this was from the preset portfolio page options)

#2-The portfolio page I would like to use (this was made from scratch, not using the preset portfolio page options)

#3-The sub-page I need to move from #1 to #2. 

Thanks! 

Hi Jenn,

Did you find a solution to this? I wanted to duplicate a portfolio, but it seems that is not possible. So I was wondering if you can move a page out of a portfolio (so its just a normal page), so similar to what you were trying to do. Did you find a way?
