Obviously the UI of the setup tool is far from perfect. One of the many 
issues it has is the fact that the import tab shows all available 
handlers, not just the available steps. That makes it hard to understand 
what happens, but is not what breaks your use case.

Your problem is the setup handler of the 3rd party product. The handler 
is responsible for making sure it depends on a configuration file. And 
should do exactly *nothing* if that file doesn't exist in the current 
profile.
