Hi Mike and Jing,

We have added this new related list to all the GRC tables for tagging the content to various frameworks/regulations. For e.g. NIST RMF and NIST CSF related content (controls, policies, policy statements/ control objectives can be tagged as NIST RMF/CSF and you can also tag them to other frameworks/regulations like SOX). Thanks for pointing out that its not documented. We will update it. I hope this helps!
