Help with Doomed Source Nexus Hamachi

[tree15]

I have two servers shown on the servers screen next to the main menu on my pserver Hamachi network.

One is for everyone and says my server name which is Cool Realms, and the other says Admin Only.
If you join my pserver client only a certain rank can join the Admin only server, which I think is pretty cool.

Now too my main point I was wondering if I could change that Admin only Nexus to be different from the everyone(regular) nexus.

But still have my other nexus everyone(regular) the same. So I would have one regular nexus for everyone that I don't change and the one nexus for admin that I would have to edit.

Do you guys see what Im saying if you can help me out with that Skype me lukecontarino_2. Or desrcibe how in the comments below. I was thinking about this idea but never new how to implement it.
