Payment approval not working in case of vacation rules

We have below requirement from client on Payment Approvals.

Payment Approval should be routed to 2 levels of approvals.
Each level will have 3-4 approvers and the first responder wins in each level. So we have created 2 Approvals groups for each level.

When any of the Approvers from level1 is on Vacation, they will be delegating the Approval to anyone person from the Level2 list
and once the delegated person approves payment, they want to send the notification to be sent to all the other approvers in leve2, except for the delegated person.

Is it a possible scenario?

E.g.: Approval Group1 has Approver1, Approver2
