change page layout php

I am using a Customizr (3.1.8) child theme. I want to set up an area on my pages similar to slider area on the home page, but with different content. I am trying to figure out what file I would change to add in a similar DIV like the #customizr-slider for the page template.

Does that make sense? I’m just having a hard time navigating through the original customizr php to find one to duplicate/edit to change this in the child theme.

Thanks!
