You can't get this list specifically, but you can see the top sites they are visiting.
Under Network-Wide/General you need to make sure you have "Traffic analysis" set to "Detailed: collect destination host names".
Then from Network-wide/Clients, click on the client. On the right hand side is a pie chart and under that is "show details". Click on "show details".
Now you will see a list of the top things they have accessed.
