Suggestion: Within 'File Groups' add ability to exclude certain sub-directories

1. What actually happened or you saw:

When creating a File Group, you are unable to easily exclude sub-directories.

Currently in order to exclude a sub-directory you must manually add every single other directory apart from the one that you would like excluded.

2. What you wanted to happen or see:

An argument added that allows exclusions to be made from within a selected directory.

As an example, the argument below would add the AppData folder(s) into the File Group, but exclude both the ‘Mozilla’ and ‘Google’ sub-directories.

E.g. ?:\Users\Bob\AppData\ -?:\Users\Bob\AppData\Local\Mozilla -?:\Users\Bob\AppData\Local\Google

3. Why you think it is desirable:

a) Allow the user to easily add excluded sub-directories within a selected directory.
b) Not rely on the user having to manually update a potentially large list of sub-directories within a selected directory each time a new one is created (by either a user or automatically by an application).
