Submix Bus Envelope Track Height

Since I can't find anything about this, I'm not sure if anyone else has this issue with Audition.  

When I mix, I use bus tracks to combine multiple tracks into one, then keyframe the volume in the envelope tab.  Here's the problem - when I increase the track height, the keyframe panel does not increase as much as the empty space above.  Why is this necessary in a bus track?  I'd rather be able to control the height of the graph on these tracks and have better control of the keyframes.  Am I missing something or can this be a future feature?
