Custom question numbers

On the "Survey look and feel" page you have the choice to use "Default" numbering on the questions, "None" or "Custom". If you choose custom numbers you can set the numbering as you wish. For example, you can use letters in stead of numbers, roman numbers etc. (E.g. 1a, 1b - A, B, C - I, II, III, IV)
