How to limit users to their dedicated IPs only?

I have shared IP for some virtual servers and dedicated IPs for some other virtual servers. By default all the Virtual Servers, Subservers and Aliases are created on a shared IP. The same story if a user with a virtual server on a dedicated IP tries to create his subserver. I’d like to limit users on dedicated IPs to use only their own IPs. Is it possible to configure in Virtualmin?


Would be nice to get any comment on this.
