Go to app.filmustage.com, and then open your project.

Navigate to the Script tab and open your project.

In the script view, highlight any word or phrase you want to tag.

From the list that appears, select the tag category of your choice (e.g., Cast, Props, Costumes, Vehicles, etc.)

Optionally enable Tag All Mentions if the selected word appears multiple times in the script. This will automatically tag every occurrence under the selected category.

Once selected, Filmustage highlights the tag directly in the script and lists it in the left-side breakdown panel under its category.
