OK Carlos I think I see what you mean.
First there is the contents object that is added to the master page, this generates a list but it does it automatically and will be difficult to change.
What I have done before is to make a button and add it to the master slide so that it appears on all of the pages.
A click on this will show a pop up which has a 'list' of thumbnail images, each image has a navigation action that will open the page.
Luckily Courselab makes the thumbnails itself for the page navigator, all you need to do is use them on the pop up and they are imported for you.
There is a vertical scrolling menu that can use images and text here.

This is on a page but it can also be on the master page to make it global.
