I've heard of a software that can sort the items using the references in the files, but I can't remember what it's called. So, somewhere on the interwebs it's possible to be lazy here! =D
Failing finding that program, anything that has a /Runtime/Support folder should have a .dsx file that has a list of the files involved with the package and would facilitate finding everything per package. That wont work with anything from vendors other than Daz though.
