Possibly, but that wouldn't break it down by machine.   And in that situation
I'd think a per-machine breakdown would be useful because then you'd know if
you should be yelling at the kid, the wife or the family dog when you get the
ten thousand dollar ISP bill.  Again, it just seems like the sort of thing that
folks would want to be able to track in certain situations.   But apparently

The separation is the gateway assignment or the lack thereof (for local
traffic).  But other than that, yep, that's a correct assessment.

Indeed, but that adds a whole new layer of complexity to my network that's not
really needed for any other purpose.
