The fastest way to do this is to create a separate window construction in OpenStudio that includes the film, and then use the Building Component Library Measure to swap out the window with the new window construction.
In OpenStudio:
1) Under Constructions tab -> Materials tab -> Glazing Window Materials, add glazing window materials to build the exterior window. You'll need to copy the parameter values from WINDOW7.2.
2) Under Constructions tab -> Constructions tab, create a new "ExteriorWindow" construction in your model built from "Glazing Window Materials" that you specified (from "My Model" at right). See the OpenStudio support docs for screenshots on how to do this.
3) Under Measures tab, access the Building Component Library ("Find Measures on BCL"), navigate to Envelope -> Fenestration section, and download the measure: "Replace Exterior Window Constructions with a Different Construction from the Model"
4) Drag and drop the measure under OpenStudio measures, and select the new construction you made to replace the existing window constructions. If you just want to apply it to only a subset of the existing windows, you'll need to modify the measure to do that. Let me know if that's the case, and I can share the draft measure I have.
