John Wayne Collection

I have the complete John Wayne Collection I would like to add to my XBMC.
I have all the movies in a folder separate from my other movies.

D:\movies\ <- main movies
D:\John_Wayne\ <- John Wayne collection.

I want to add the John Wayne Movies but I want them only to show up as
1 spot (ie. John Wayne Collection) when I look thru my other movie (like say a "Die Hard Collection" shows up you select it then see the Die Hard Collection)

Is there an easy way to do this since there are in a separate folder or do you have to add them to a collection 1 at a time (Over 100 movies thats why Im asking).

Thanks in advance...

Movie Sets

In my opinion the easiest way to create a movie set is using XWMM. There if you enter each movie you will find the tab Other and there you can associate this movie to an existing set. To create a set or organize it go to the menu Tools > Manage Movie set.
