Can we update IRC_CAND_EMAIL_MESSAGES Table through HDL (Candidate.dat / CandidateJobApplication.da)

We are trying to update certain email sent from the system as they contain sensitive information. We need to bulk update the email sent from the system to the candidates. We are searching for an option to update the Interaction message of the candidates through HDL. Candidate Interaction Business object only masks the IRC_INTERACTIONS table. We are in need to delete the IRC_CAND_EMAIL_MESSAGES table. Please let us know is there anyway in HDL to update that.

Thanks,

Siva
