Reply to S4 Pro effects?

I have a question about the effects on the S4, I often use delays & reverbs but find the the effect isn't post fader, I.E. I knock the line fader down or the cross fader over I lose the delay/reverb tail.

Is there any way to make the effect post fader?

I don't understand why these effects are not post fader this is the 1st version of Traktor I have used so I'm not used to the NI effects. Before this I used Serato Scratch Live with my DJM 909 so I'm used to the echos & reverbs being post fader.

If any one could shed light on this, is this the way it has been in older versions on traktor?
