Hello:
Is there a way to access the expression that shows the list view if I have to customize the look/feel of that page?
Thank you.

Nope. You can create a grid with the same record as data source and plug that interface to the site.
You can configure that using readOnly grid with record.
You can have access to the code by clicking on the button below but only for the grid's code. Not more. If you want more, use gridField() on an interface and use it on the site.
