Reseller account total bandwidth and disk space

Hi!

Is there any way that a reseller can see the total bandwidth and disk space used by all the sites he's hostng?

That is: I have a reseller that has, for example, 10 hosted sites. How can he know the total bw and hd space used by all 10 sites?

I, as root, can see the reseller's stats in the /scripts/statres?res=reseller page.

Is there a way the reseller can see he's own stats?

Thanks!
