It would be nice to see this be a true change all. For example we have a basic setup for one service that always has the same name, when we went to change the name we had to change all of them one by one. They came up in the Multiple services editor but the topic/name had to be done one at a time. It took a lot of time to make a years worth of changes.
I've put a request in to help make this better in the future.
