Unless something changed before I used it last, the insert location will depend on how you add an object, i.e. -add: vs -insert:, as well as any sorting settings. Using -add: should always append to the end of the collection as long as it is unsorted or does not re-sort automatically. If you use your own method to add new objects, you can do whatever you want. No need to customize much.
