EXS 24 Logic Sampler Users Group

I want to combine instruments. For example, I have timbales in one .exs 
instrument and timbale fills in another and want them together.  I know 
I can load individual samples, but is there a way to load the 
information from one file into another (combine the two really) using 
the .exs files?  Giga does this and it is a big time saver (when the 
Giga editor doesn't crash the computer, but that's another story.)

Thanks,
Michael A. Levine
