MyMovies Pro has a list of useful criteria on which one can sort one's movie collection. However on sorting by Director the forname is used. I find this far less useful than a surname sort as, especially for directors from outside the US or Britain, I may well not remember the forename. In any case the surname is likely to be less redundant than the forname (I have 7 Johns, but only one Frankenheimer), and who would do a Google search by first name? How does Wikipedia list people in a particular category?

Is there any way for setting the sort criterion to surname?
