EXS 24 Logic Sampler Users Group

I'm in the middle of creating large instruments with at least 49 
samples with my EXS24 instr. editor.
Now, all the samples need to be 'one shot'. Is there a way to this 
with all the zones at once? It would save me hours, and I would be 
highly surprised if it isn't possible!
Any advice is appriciated!
