Assign a Task Escalations (not reminders) could/should serve as an SLA guardrail, allowing an escalated alert to be sent to a supervisor, oversight group, etc...however, because the Escalation includes all original assignees, this limits the use as we do not want the client (Requestor, initiator, individual who completes the Form that starts the workflow) or the associate(s) to whom the task was assigned to be notified of a potential SLA breach.
While there are examples when copying everyone makes sense, there are also many cases in which this escalation should be limited/targeted to specific individuals or groups.
Utilizing separate emails (requiring separate entry for all emails to be included in the Escalation email, rather than automatically copying the "Assigned to" Emails from the task) for the Escalation (not collecting emails from the task assignment) might allow for the Escalation to function both ways.
