I see, it is clearer now. There is a feature that you might not be aware of that might help. When you modify a step type's settings, you can check the "Apply change to all instances of step type" checkbox near the bottom of the step type properties dialog. If this checkbox is checked, all currently loaded instances of the step type will be updated. It perhaps isn't ideal though or exactly what you are looking for. It should be possible to write a tool sequence for the tool menu that does pretty much what you are asking for though.
