Integration of Two Radio Buttons on a Dashboard?

[TAE]

I don't seem to be able to integrate two radio buttons on a single dashboard to achieve the following selection logic.  Each radio button has two options and an "OR" condition on the 2nd radio button.  The choice from the 1st radio button drives the 2nd radio button to display 1 of 2 different ways.  Drawing of selection logic follows:

                                                                        RB1

                                                          State1        State2

                                                RB2                 OR                 RB2

                                 State1a       State1b            State2a         State2b

Explanation of drawing:

In RB1, if State1 is selected, RB2 displays State1a and State1b for selection OR if State2 is selected in RB1 then RB2 displays State2a and State2b for selection.

Is this possible, if so, how can it be accomplished on a dashboard in simple XML?

It's possible.  Have RB1 offer the user choices "State1" and "State2" and put the reponse in $token1$.  Have RB2 offer the user choices "a" and "b" and put the response in $token2".  Add a <change> element to RB2 that sets $token3$ to $token1$$token2$.  Use $token3$ in your query.
