How to get list of promotion request approves selected by a user?

Hi,

I have a requirement where i want to get the approvers selected by a user in the "Set up Participants" tab for promotion request?

For Instance, In the promotion request workflow the Creator gets a task to select approvers in the "Set Up Participants" tab, i want to get the list of those participants selected by him.

Please help.
