Story days, a.k.a. Script days, are important to identify for continuity and are vital for the art, costume, and hair and makeup departments, as not only will characters' clothes change with each story day, but there may be other physical changes, too.
StudioBinder's Breakdown feature makes marking Story days a breeze, just follow these steps:
Step 1 – Navigate to the Breakdowns page
From your project overview page click on the Breakdowns button in the Breakdowns menu.
Step 2 – Enable the Script Day Column
Click the More button (⋯) and select Customize Columns. Then enable Script Day.
Step 3 – Label Days
Fill in the script day column with the script day that corresponds with each scene.
