When logging in to a D2 application, how do I set focus on a specific widget?

I have a D2 application with a workspace xml file that creates the layout. When a user logs in, the focus goes to the last widget in the xml file. I would like the focus to go to a different widget (viewer), when a user logs in. How can I configure D2 classic to do that?

Please refer to the attached workspace xml. On login, the focus goes to 'Workflows' widget, and I would like it to go to the 'BravaCSR' widget.

Thank you,
