Catalin.b on SD3 cymbals replacement.

Hello,
How do you replace multiple cymbals?
When i try to replace i got all the cymbals from the overheads recognized as only one cymbal and after that i move them in the midi editor to coresponding cymbals to match the original groove. A problem with this method (besides the time consuming factor) is when i move the midi notes is almost impossible to put them in exactly the same place as they are played in the original rythm.
