domain name change

I need to submit a new site to the OD for a company who already have one other website on the OD listings. (Two separate domain names).The problem is it is the new site which the company would like to be be submitted for inclusion on the OD in favour of the second site. Given that it is the OD policy to accept only one site per company, how do I indicate which site the company is requesting approval of. Can I do this by requesting a change of URL/domain name?
Thanks

You can put through an Update URL request. Type in the old URL, click Next and then in the screen where it shows you the existing listing, change it to the new URL and the submit it, giving a reason.

You can then request for status updates in the Site Submission Requests forum.
