For what it's worth, I have rolled-out Phase 1 of the previously-unreleased listing feedback features. You (as the Realtor) can add listings (by MLS ID) to a Vistor's Favorites, and the Visitor can provide feedback on any listing in their Favorites (rating 1-5 + comments), which you can also see in the backoffice.
Phase 2 will entail the full ConnectMLS loop (rounds of properties for consideration, etc.).
Let me know if that helps.
