Apply redirect to multiple terms at once

Issue Summary

I would like to apply a taxonomy redirect to multiple terms in a vocabulary, but not all of them. Right now, I need to apply the redirect one at a time. Even if I select more than one term, it only applies to the first term.

Vaguely related to this issue, the solution of which appears to destroy !parent_names: http://drupal.org/node/325132#comment-1594318
