EXS 24 Logic Sampler Users Group

Just got the EXS and I have a couple of questions. Importing 
some gigasamples like pure drums, if I want to group all my
snares together do I have to open each velocity layer and assign 
it to a group. I can't seem to find a way to select all the samples
assigned to one key and group them together other than 
selecting each of the sixteen velocity layers individually.
The copy of EXS i bought turned out  to be a send in the cd
version. Tried to load in the samples from the installation disk
but the EXS can't see them. They are in the correct sample
folder. Any ideas?

Thanks for any help
