The Hub - configurable URL

When we click a link in the Hub to jump to a site for continued maintenance, there can be issues with where it goes. I'm requesting an enhancement which allows a configurable URL where we might want the Hub to go rather than the default. For example, I have a lockout against direct access to /wp-admin. I have changed my login page to /login-on-this-other-page (not really, that's just for this example). So every time the Hub goes to my site there is a Denied message. A custom that would eliminate that error. Thanks!
