Real-time Bandwidth usage of ALL devices

Please provide an option under the "Activity" tab of the app to show real-time bandwidth usage of all devices at once.  I know you can see usage for each device by clicking on the device but I'm talking about a list of all devices showing their current usage on one screen sorted by what's using the most bandwidth.  Similar to Activity Monitor on a Mac or Task Manager on a PC so you can see what's putting the most demand on the CPU.  All devices listed with its current usage next to it... in real-time.  Perhaps a real-time total bandwidth being used at the top of the list would be nice as well.
