Block response Branded with more information

I really like the possibility to customize the branded block page. If i understand it right, there will be an information why the page is blocked on the roadmap. Is this information correct?

I would like to have the possibility to add the blocked page Domain (like www.example.com) as parameter added to the External Link URL. For example: https://myhelpdesk.com/incident?BlockPage=www.example.com

Would this be possible?

It would help my Users to send this information to our Ticket System.

Thanks!
