The situation is as follows. There are users in the system - bosses and their deputies. Everyone has different tasks and different rights in Jira.
A substitute must receive a notice of the chief's tickets by mail if he has the same rights to this ticket.
The way I see the problem:
If the boss gets a role in the new ticket, then the deputy should be automatically substituted by the observer. (Automatically, because those who create the task will forget to set the deputy as an observer)
Is it realistic to implement this using standard Jira tools?
