I have the Movies folder in my macbook drive and a folder called Movies Of Mine on my NAS drive. Folders with the word Movies in the name allow you to add columns like Duration, Dimensions and Codecs. For each subfolder within the Movies folder I want the Duration column to display by default. How do I make this happen?

Manually one by one...
