Using Outbound Email Accounts for Security Group

I want to use Outbound Email Accounts for Security group. Each user should see own outbound email account in campaign wizard. But there is no relationship between Outbound Email Accounts and security group. There is a settings in role for Outbound Email Accounts.
How can do this?

You have to do 2 things.
1: From CRM default Email Settings, uncheck the checkbox to “allow sending from this email account”
2: Ask each use to edit their profile and go to Email settings in the bottom, and then add an outbound account for them.
So in this case a separate email account will be configured for each of the user.

You cannot do it via roles or security groups. This is something else.
