Logic Pro 9 EXS24 import multiple samples-Help!

I'm trying to load a library of 48 wav samples; I load samples and when it ask me how to do the map I choose Contiguous Zone , zone width 1 , start note C1 >ok.
Unfortunately the samples pitch is set to C#-2 for all zones and so is a annyng work to change values manually. Anyone knows where I'm doing mistake?
