Bandwidth Reports?

Hi Guys,

I'm using Piwik with import_logs.py in replace to AWStats, but one of the main features I can't found into PIWIK is the Bandwidth used by the site... this report exist?

Here some detail about what i'm searching

Bandwidth:
Total number of bytes for pages, images and files downloaded by web browsing.
Note 1: Of course, this number includes only traffic for web only.
Note 2: This number does not include technical header data size used inside the HTTP or HTTPS protocol or by protocols at a lower level (TCP, IP...).

thanks in advice!
Ale
