Chop Threshold for end point ?

I have a run of five slap bass hits in one sample and want to chop it up. The threshold will allow you to get a tightish start point for each hit but then it doesn't behave in the same way for the end point and gives you the seconds of silence between each hit.

Any way to get it to recognise the end point of the wave and cut accordingly ?

Unlinking slices then setting threshold ??

Thanks guys.
