 From http://www.squid-cache.org/Versions/v3/3.0/cfgman/:

  Configuration options can be included using the "include" directive.
  Include takes a list of files to include. Quoting and wildcards is
  supported.

  For example,

  include /path/to/included/file/squid.acl.config

  Includes can be nested up to a hard-coded depth of 16 levels.
  This arbitrary restriction is to prevent recursive include references
  from causing Squid entering an infinite loop whilst trying to load
  configuration files.

So you could define unique_hostname in a file (different on each server)
that is included by the main config file (which is the same on all).
Squid 2.7 also supports the include directive.
