No, you have to actually do it in your tag. The Django trunk now has an assignment_tag (See: https://docs.djangoproject.com/en/dev/howto/custom-template-tags/#assignment-tags) to allow you to do this easily, but until it hits a release, you'll have to do it the old fashioned way. See: https://docs.djangoproject.com/en/1.3/howto/custom-template-tags/#setting-a-variable-in-the-context
