Using multiple websites for coop

How do I use put multiple sites in my coop program? The site I have in the program now isn't indexed by G yet but I have other ones that are. I couldn't find where to add another site to my account. Under 'Edit account settings' there is only space for 1 website URL. I want to add my other sites to my account so that I can get more weight.

 

You need to open a seperate account for each and then bind them in the Control Panel.

 

Thanks!
