Mark a missed call in the call queue as called back

I would really like a feature so that our Account Managers who are all on a call queue can mark a missed call when they have called the customer back. We have been having some situations where multiple Account Managers will call a customer back because there isn't a central place to mark that the call has been returned.

I have tried having the Account Managers delete the missed call from there view in the app but it only applies to their personal account and not the call queue, so this will not work as a solution to my problem.

Does anyone else have ideas or share this issue?

Best,
