I would like to see a field for Group's manager. This would allow you to create an automation that says "after X amount of time that ticket is overdue, send a notification to <<GROUP_MANAGER>>.
Right now, I'll need to create individual rules for each group I have which obviously isn't the most efficient way of doing this.
Yep. As you mentioned, right now, you can set escalations within the group from admin.
We have taken your feedback into consideration and the same will be implemented down the line.
