submit button under BuddyPress save button.

I am going to create a public profile directory website using BuddyPress .
Users will register, then complete their profile, admin will check the information and manually approve them for the directory listing.
but the problem is, I don’t want to waste my time checking incomplete profiles, also I don’t know when they will complete their profile, today or a few weeks later.
so I need a submit biodata button under BuddyPress save button. after filling the required fields, the user will be able to click this submit button. admin will be able to see them separately from incomplete profiles.
I don’t know how to do this.
