BlueID simplified login user experience for fed auth

For IBMID users that use BlueID to fed auth with a customers SAML authentication system, BlueID, presents the same login screen for all customers and has a hypertext link requiring the user to either enter their userid (e.g. bibaer@cisco.com) or click the link, "Login as Your Company".  These two mechanism then send you to another weblink asking if you are part of Cisco which then send you to another screen to enter in your full credentials.  This follows with a customer's fed auth asserted login screen.  The totality are roughly 4 screens for a customer to login to an IBM Cloud property like Bluemix dedicated.  The first screen could be removed if we were able to provide a dns entry for our BlueID page that is specific to each customer.  This would improve the login experience for each user.  I reference Box as a more simplified experience for login that would be desirable to emulate.  If you go to www.box.com then the existing IBM experience applies, but if the user goes to ibm.ent.box.com then they skip the first screen and it assumes you are part of IBM.  We need a means of requesting a DNS entry on the public internet for the equivalent of ibm.ent.box.com and linking it to our second login page in the BlueID login process.
