i have two single woocommerce installs (not multisite) that publish the same content (products etc). i want to add a cross domain level rel canonical to the second domain, such that -
www.domain2.com/any-url/ will have a rel canonical of www.domain1.com/any-url/
it seems only way to do it is add rel canonical to every single URL manually. is there not an option to set a top level rel canonical for the whole domain?
