They are the same application yeah - with a few configuration differences, mainly in the initial permissions setup whereby the noticeboard allows all site members to add content but the weblog does not. (this can be easily changed by modifying the permissions settings for each app).
There's no easy way to add more I'm afraid. What is it that you want to do - maybe there's an easier solution than having several copies of the app!
Thanks
