EXS 24 Logic Sampler Users Group

I'm prepping for a tour in Europe and need some information...

I notice that you can use the EXS zones assigned to groups and
control various things with 
that.  However, the brand new manual seems to indicate that you can
offset the filter, etc. 
in each group to sort of do layers.  Well I'm running the latest
greatest versions in  OSX 
and guess what?  No offsets to filter or anything for a group.

Any thoughts?

Thanks
