Add a pop-up page under a collapsible row using existing structure - crave theme

[rackrake]

I am using the theme crave.

On its main product page, there is a section to add a "pop-up" page, it is called a "pop-up link text" and what it does is that it hyperlinks any text you write using that section and makes said text clickable to make a pop-up page appear, (any existing page that you have linked can work)

Another section on the main product page is called a collapsible row.

Now,

I want the exact pop-up section, but to appear inside a specific collapsible row's text of my choosing. 

Is this possible using existing structure available for pop up link text, and doing any complicated html stuff, considering i am quite terrible at that stuff.
