Collections with the same name

In SMS 2003 you probably noticed that you couldn't have the collections with the same name unless they were linked collections. Through one of the tools I was creating I discovered that you can create as many collections with the same name (different IDS) as you want in SCCM 2007. This poses a problem if you have a tool that is searching for a collection name. Now you could have 2 or more collections that have the same name and different IDs.
