No, no such "macro" capability exists, to my knowledge.

OPTIONS:

If you're using a remote-execution facility (e.g. ssh, Kerberized rsh or
whatever) to distribute the conf files, perhaps you could call a wrapper
script to localize the query-source parameter.

If your "options" statement never changes, then perhaps you could have
each machine "include" a file which would contain a localized version of
the "options" statement (ISTR that later versions of BIND 9 will even
let you do "include"s *inside* the "option"s statement, so maybe that's
another possibility).
