Ramdomize the blocks while selecting a specific selection for a block in real time

[David McFarlane]

You could achieve much the same effect, without 
any inline code, by using a main List with 
Selection Order set to Counterbalance, and Order 
By set to Subject.  That List would have one row 
for each of your possible scenarios, and then use 
the Subject number to select which row to run.
