Not submitting SAT Subject Test scores to UCs?

I know we can’t use Score Choice when it comes to sending SAT scores to UC campuses (i.e., we must send all of our SAT scores to the UCs), but does this apply for SAT subject tests, as well?
What if you take a test, but do not want to send your score to the UCs? Is that ok, or are we required to send all subject test scores, too?

Anyone? :-S

The University of California does not require SAT Subject scores. The official language in the admissions policy is that an applicant “can” include them in order to demonstrate mastery, and some campuses recommend them, but they are not a required part of any applicant’s packet.
