CTA Comments similar to Timeline Comments

We’re about to go live with our migration from SFDC edition to NXT edition and one of the significant downsides our UAT users have noticed is the inability to use Chatter or similar commenting functionality on the CTA detail view as they could in SFDC edition. The bare minimum we would expect here is Comments similar to what’s on Timeline updates. Internal collaboration is key and having it documented within Gainsight rather than hidden away in emails and Slack messages is not the route we want to go back towards.
