Modern[1] Squid versions should remove old same-name annotations when
adding new ones. If you are running a supported version, and your Squid
merges/appends annotations, consider filing a bug report.

With modern Squids, you should not do anything special to accomplish
that. Only the latest annotation value should be preserved. If that is
not happening in your tests, consider filing a bug report, especially if
you can reproduce with Squid v4+.
