AI control of Track Delay

Hi All,

I have just bought a CC121. Very disappointed to discover I cannot use the AI knob to adjust the Track delay from the Track Inspector. Is there any way I can control the track delay with the CC121? I use track delay to time align drum mics as well as DI and mic bass tracks. It is frustrating trying to use a mouse for this as typically I need to set the track delay in the order of milliseconds and the mouse has a much finer or coarser resolution. Any suggestions?
