Domain Mapping requirement - site admin can edit all blog's domains on one page


I've got a requirement for our WP-MU system, where the domain mapping for all the blogs in the system needs to be done by the site admin. This means, one (site-admin's) admin page to manage (view, edit, delete) all blogs with domain mappings.

Currently, we can't do this right? - site admin has to go the backend of each blog and key in the domain name for that particular blog.

Is there a workaround? or some other plugin i can use to manage these domains in one page?
