My artist has submitted sprites to me and they have been named in the format "spriteName_1", "spriteName_2" etc, and a few animations go all the way to "spriteName_100".

The default sorting mode in the application arranges the sprites in the order "1, 10, 100, 11, 111, 12..." and so on.

Is there a way to make it so that they're sorted in the "1, 2, 3, 4..." format?
