Not that I am aware of. However if you put it in modem mode and use your own router you will likely have more data and analytics available to you. Eg with my Asus router I can see traffic flow and web history per device over whatever timescales I choose and could, if needed, therefore deduce what device was online when on a historical basis (assuming a mimimum data flow).
I'm not a Very Insightful Person (just a little bit, sometimes). I don't work for Virgin Media (but then nor do any of the offshore customer service agents).
