When modeling behaviors in activity diagrams, it often happens that the lowest level elements, opaque actions, are later identified to be a bit more complicated than expected, and therefore better described as the usage of another activity, i.e. as Call Behavior Actions (CBA). Remodeling by deleting the opaque action and creating a CBA is cumbersome, therefore I've created a script-based solution for it.
Please read the attached Word document, which describes both installation and use, for further information. The ZIP contains two the component sharing files for the import into a model, one just the script and one with the script and an example.
