Physical Channel Numbers?

Is there some way to get the Channels app to display the physical channel number, and not just the virtual number? (Using an HDHomeRun.) I was hoping it would be in the detailed info under Options (alongside codec, bitrate etc.).

Or, failing that, any way to get the info out of the HDHR even without Channels?

You can get the RF Frequency for each channel from the HDHR.
