Ability to hide other hosts or incoming connections only option

I use RealVNC on a variety of servers in disparate networks (different customers) where a VPN isn't possible. With RealVNC Server 7.x there was no GUI option that showed other servers on different customers that I singularly manage. I don't want to see those options in RealVNC Connect 8 and want an option to disable them. 

I'd like for an option in the installer or in configuration files to disable showing a list of other machines on a Windows server. When there are multiple other admins on that network (that don't use RealVNC, only I do) I don't want them seeing a list of other servers. Same goes for if I get remote support from a vendor I don't want them seeing a list of other servers that might get nosy about. Or worse yet, I don't want a cybercriminal seeing a list of servers and then using it as an opportunity to bruteforce them.

Another option would be in the install which we could choose that our install were 'incoming connections only.' Or an option to password protect the GUI from other admins or 'curious' individuals.
