Woocommerce attributes page on wp-admin

Hello,

Is there any hook for listing and saving attributes on attributes wp-admin page?
http://i-menu.com.br.s159004.gridserver.com/wp-admin/edit.php?post_type=product&page=woocommerce_attributes

I’m wondering if it’s possible for example to bind a user and an atrribute, using a usermeta saved on attribute creation for control listing

Thanks ind advance!
