Developer Comments in Customer Expression Window


Does any one know if there is a way to have developer comments in the expression window like you can when writing SQL?  This is useful when you are writing complex formulas.  For example, in SQL I would do:

    Select case when col1= 'Test' then 1 else 0 end as test1 --this is test #1--

    from table1;

Is there a "--" method to do this in Spotfire?
