HDHomeRun Extend - Adjust Hardware Transcoding per Channel?

I own an HDHomeRun Extend TV Tuner, which has the ability to perform hardware transcode. Does anyone know if I can customize Plex to turn off/on/change the transcoding on a per channel basis? Currently, it is an all or nothing global change per TV Tuner.

HDHomeRun has the ability to do this based on URL calls, so it would theoretically possible.
