Plans for implementation of new CUI Rules for Doc Category Field

As you probably know, Fed Govt will soon be implementing new Rules/requirements for categorizing information as "Controlled Unclassified Information" (CUI). This will replace the document categories previously call SBU, PRA, Privileged/Proprietary, PII etc. NARA's Information Security Oversight Office (ISOO) has issued Implementation Guidance on this to all Federal agencies calling for development of "deadlines for phased implementation by agencies" including an assessment of systems containing CUI and a plan for transitioning to the standard (CUI categories/subcatagories) within the coming year. See CUI Notice 2016-01 for more details at :

We're wondering if you have yet started looking into these required changes and if you have any plans yet for when and how they will be accommodated in TechDoc's Document Category required metadata field.
