One install, 14 blogs, assigned to different users – possible??

I have a 3.0 install. New to WP. I am seeing if I can move an existing site that has 14 blogs over to WP. What I want is pretty darn basic. I want to move all 14 blogs over to one singular install so that everything is managed together, and then be able to add 14 users to WP and assign them to their corresponding blogs. From all my searching it seems that WP can’t do this. Which just baffles me.

I saw this thread here, YES I searched before posting:

…where moderator “Samuel” just shut him down and locked the thread. Well excuse me Samuel, but his question was not answered, and your actions were just plain rude. Why did you not just answer him? You claimed he asked the same question in a previous thread, but he was asking about a 2.9 install in that one. Why so rude, why so rude? If you had actually bothered to answer him, I would not be having to create yet another thread on the forums. You just prevented the people like me that follow good netiquette in searching before asking from having to add yet more clutter to the boards. Now I have the identical question…

Now hopefully someone with a little more patience and politeness can help me with this question before you tell me that this has been asked before and to search the forums before posting ??

Thanks.
