How do you set the previously selected radio button in a script?

[#1]

I have created a script which includes a call for a modal dialog box which has (2)radio buttons. I want the dialog to open with the second radio button selected. Everything I have tried results in the the default first radio button being selected. In fact ultimately, I want the dialog to open with the previously selected radio button selected.
I have scoured the online manuals, online example scripts and JMP script guide to no avail.

The following works for a non-modal dialog, but I don't think there's anything similar for modal dialogs:

New Window( "Example",
rb = Radio Box( {"single", "double", "triple"}, Show( rb << Get() ));
);
rb << Set(2);
