TRACKING OFFSET

It is sometimes difficult or impossible to get tracking to actually select exactly where you want! ...no matter how many times you try it selects another (nearby) "object"! Sometimes you may want to track but not center the frame on the selected object! Give each tracking segment an X and Y offset that would adjust its framing! I find the tracking usable maybe 4 out of 10 times that I try and think this would bring it to maybe 8 of 10 times!!! ....That would be awesome!!!!
