EXS 24 Logic Sampler Users Group

I've been doing a lot of EXS editing lately and it would save me a
huge amount of time if there was some way to edit multiple zones at 
once, e.g.

(1) to assign multiple zones to the same group in one operation,

(2) to be able to drag select multiple zones at once (the only way I
know how to do a multiple selection now is to manually shift click 
every one)

(3) to be able to change the numeric parameters for a bunch of zones
at one time.

Thanks
