Hello David,

Unfortunately there is no automate faction for something like this.

For tickets already in the system the Assigned to field on a Action Item will have to be changed manually to a different approver.

You can make the assignment change on the template used by new ticket to make sure the Action Items  are assigned to the proper admin.

A workaround would be to also use the Admin group on the action item and it should allow any member of the group to make changes.

There is also a supervisor that can be set for Departments and Companies in the environment and they will have access to all the tickets assigned to the members.

In case you require further assistance don't hesitate to reach out if you require further assistance.
