depends if u r doing this for a short sound or constantly over the track...

Constantly .. I can think of nothing else that a reverb that has the preset of reverse verb... lots of old hardware had it.. so I at least some plug ins will.

for short sounds... just do a copy ... reverb efx 100% wet... reverse that .. add it in another audio track... U can even use automation to control volume etc.. This should do the trick nicelly!
