Mix Playback Quality

Whenever the KDP is playing a video there is the option (assuming that "Flavor Selector" is enabled for the player) to select a bitrate/flavor for playback. However, when playing a mix the option is blanked out and you are unable to select the bitrate/flavor to playback. The KDP appears to be playing back the editable version of the video when a mix is loaded. Since the editable version of the video is poor quality it would be better if a flashvar could be set so-that the mix would pull in the quality level you needed for playback or perhaps enable the "Flavor Selector". Is this possible or is it done already?

Thanks!
