When pulse alert is sent, make it clear if this is a change from a previous pulse

My users get alerts in both Slack and email when a client is set to High Risk. The problem is, it causes a lot of anxiety when they see this, but it turns out to have been a continuation of an existing High Risk customer. It would be nice if the alert in both email and Slack stated if this was a change or if it was a continuation (not just depending on the icons).
Also in Slack, the colored icon is a small to a large version of the pulse box, which some users unfamiliar with CS saw as a "worsening, because it was bigger".
