Enhanced Prompt for Variable – Add Hint to Checklist

Hi – I am using this Action in order to let the user choose what to compile. He gets a List (that is built dynamically from an INI file), and selects his choices. It would be great if I could add a hint to each item in the Checklist, when the User places the mouse over it or in any other way (maybe clicking it will write the hint in the bottom of the screen). I know that I am asking a lot, but this shows you how much I use this action.
Thanks Daphna
