importing / merging a patch from one show to another

Hi Folks:

I am setting up a new show on my Hog3PC, and i would LIKE to be able to import the patch from another show, to save rebuilding the entire thing. i have not (yet) been able to locate it in the manual, (thats not saying its not there, i just havent found it yet)

Can someone please enlighten me?

Thanks a TON
TIM
