I think I might have figured it out, by editing the .dset XML code directly I can put the full path name to
Code:
Library/Application Support/Super Duper!/Copy Scripts/myincludescript.dset
which seems to be working. Is there no way to do this in the GUI, only through editing the xml file? When I load the copy script in the GUI it does display the entire path name correctly. seems like if I choose an include script to use with a full path, SD ought to just remember that.
