We have an On-call schedule in which Person A may be on call and ask persons B, C, D, and E to take over a shift.
The On-call column is a contact email list.
Persons B, C, D, and E will receive an Update Request to identify if they can cover that shift.
Persons B and C respond that they can cover the shift.
Person A will make the choose which one will cover and make that change. An alert notification is sent out to the person who is chosen.
The original requirement was to let all team members know that a schedule change has occurred.
Now if person B is covering the shift, they only want person C from the above example to receive a "thank you but this shift was covered" alert notification and no other communication to D and E.
Thank you.
