Send email one at a time to multiple people picker

I have a list that has a people picker that accepts multiple value. I want to start a workflow that would email to all the value in the people picker one at a time.. Is this possible?

Scenario: People picker has two values, person A and person B.

When I submit the item, an email will be sent to person A and after button click an email will be sent to person B. It's like an approval workflow.
