Creating a list of Internal pages - from Open transitions

I have created a segment to look at users that visit a specific page.
Now I wanted to get a list of the Internal pages that I can get from the ‘Open Transitions’. This is so that I can include this list on the e-mail reports.

I created a Custom Dimension called ‘Internal Pages’, but I don’t know what to do next e.g. what code I need to add on the page.

Is this the right step? Or there another way of achieving this?
