Data Usage by Client SXR80?

Hi there, seen a million similar threads related to this, but nothing mentioning the SXR80 specifically.  I'm assuming the answer is "No" based on related threads, but is there any way to monitor specific device data usage on the SXR80/SXS80?

I've got some device going haywire and eating up my data cap, but the "show statistics" in Advanced seems extremely unreliable, it seems to not adjust quickly.  This page seems to indicate there is a "number of transmitted/received bytes" section, but that doesn't show in my Insight page.

When I look at the Usage : Traffic Widget, it only shows the total router traffic, that seems to be the only "client" listed.

Any help here would be appreciated, thanks!
