speficy a different owners group for a site.

how do i change the owner group to some other group for a subsite.

When we try creating a site from the default web dialog, then it asks for specifying owners, members, visitors. When the owners group is set as the group for approval when we click site settings - site permission - access level settings from the ribbon.

Canw e change the default group to some other group other than the specified owners group
