Which report, or custom query can be used to get Office channel information?

Since Desktop Central can determine which patch a paticular machine needs based on whether or not the machine has either the Enterprise Current Channel or the Enterprise Semi Annual channel, which report or custom query can be used to get a report of which Enterprise Channel each machine is in?

I need to be able to pull a report that reads somwthing like, "These "X" machines are in the Semi Annual Channel," these "X" machines are in the Current Channel," these "X machinses are in the Enterprise Monthly Channel.

I can do all of the filtering afterward, I jsut need to be able to pull a report that lists which channel each machine belongs to for security updates for the office software.
