macro for query-source option?

[D.M.]

I have a distributed environment where 1 server distributes a single
named.conf to several machines.  Now I have the need to add the
query-source option so queries go out the public admin interface on
those several machines, however, that interface IP is unique to each
machine (of course) so I can't put a static value in the master
named.conf.  Is there a macro or someway of having query-source use
local info for this option.  Say something like:

query-source address <local FQDN's IP> port *;

hope this makes sense.
