Option to Remove DFS Channels from the Auto Channel Selection on ePMP 2000

I would like the ability to remove the DFS channels from the Auto Channel Selection on the ePMP 2000.  Our ePMP always seems to select a DFS channel.

Better yet, like the cnPilot, have an option to prefer non-DFS channels and an option to exclude DFS channels. If it cannot find an acceptable non-DFS channel it will resort to a DFS channel. If the prefer non-DFS option is selected maybe have it reevaluate the non-DFS channels at a regular interval and if it finds an acceptible non-DFS channel it will switch to that non-DFS channel.
