You could write your own action method to take the place of the -add: or
-insert: action method that is normally connected to the Add button. Your
custom action method would call the appropriate NSOpenPanel methods, then
call the -add: or -insert: method, or the underlying -insertObject: method
from Core Data. In Interface Builder, you would disconnect the existing
-add: or -insert: method, then connect your new action method in its place.
You would normally implement your custom action method in a subclass of
NSWindowController for your window.
