Add option to keep duration of mixed down file same as track (ignore effect tails at end of track)

It would be great if on the Mixdown dialog box, there was a check box something like this:

[  ] Don't let effect tails increase track's duration

Currently, when you mix down a track, it may add a second or two to the end of the track to handle the tail of any effect, such as the decay in Reverb.  For Radio (which is what we use Audition for) you need very exact, clean, tight edits.  The extra duration that gets added from certain effects is a big problem.  We get around it by using automation and cutting off the envelope for the effects a second or two before the track ends, but that is a lot of work when you're dealing with hundreds of tracks each week.  It would just be great if we could check or uncheck a box to have the rail of any effects automatically cut off, so the duration stays the same.

(You'll also see a lot of people on the forums very confused why the length of the mixed down track is larger than the track in the editor.)
