How do I 'except' or 'negate' a regex host_name in a service definition?

Maybe something like:
define hostgroup{
name my_filter_group
alias mfg
members {^chi-[a-z0-9]*-sim-[0-9]$}
}
Then in the services definition use
define service {
hostgroup_name !my_filter_group
host_name <some regexp matching all hosts>
...
}
Sadly you will end up seeing the hostgroup in the CGI, but.
