Named ip_addr lists?

[Richard Johnsson]

It sure would be nice if there were a way to name a list of one or more ip
addresses. Something like an acl (an ipl?) but restricted to ip addresses
only. Then I could give a name like "stealth_servers" to a bunch of ip
addresses and use that in also-notify statements rather than repeating all
those addresses in several places.

Has this been considered? Have I missed it hiding under some obscure name?

A simple text substitution macro facility would work too, but I won't ask
for that. :-)
