This default is just for when adding a new administrator. It gives you a shortcut so you don’t have do the same clicks each time.
What you request is not possible. How can the login form know what default to present for different potential, but as yet unknown, users? If they had the full SmartConsole client, this will be set after their first login.
The only way the web console can do this is via a locally stored browser cookie (what they were originally designed to do). You’ll likely have to do a TAC case and/or RFE for that. Achieving this is a 100% server side operation.
