Centrally backup SMS/MMS messages in Archiver

I would like the ability to centrally backup/archive SMS and MMS messages for Documentation, Audit, and Compliance purposes (HIPAA) using Archiver. We already have the ability to centrally backup call recordings and messages but not SMS. In Healthcare, there is a need to document SMS consents that are currently being done manually. The sms/mms messages are needed for proof. There is not currently a way to do this according to support and developer support for the APIs
