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.
