It may be helpful to add a feature to the "Conversation" dialogue box that reads, "Smartsheet (SS) COMMENT ADDED MM/DD/YY" and\or "Smartsheet (SS) COMMENT EDITED MM/DD/YY".
Without the quotes as I quotes mean something totally different in the world of coding?
It seems like it already has the date. Are you asking for the addition of the text "Smartsheet (SS) COMMENT ADDED/EDITED ..."?
