How about a duplicate tool?

I really want a server duplication option so that I don't have to remake the exact same thing if I want multiple with the same concept, but for different topics. Also, a selection tool would be nice, so you can choose to copy the messages inside selected channels, not all of them. Now, another selection option would be to duplicate a channel and select the categories it might go in. This isn't a huge feature, but it'd be nice.
