software-related Sorting by Custom Categories in Movie Magic Scheduling?

Hi there,

I've created breakdown sheets for the first five pages of my screenplay in Movie Magic Scheduling as a preliminary test.

When sorting the scenes, the selection appears to be quite limited. I need, for example, to sort scenes by actors and by special equipment.

Is there a way to add categories, or do I have to enter the most important info for each scene in a field that is usable in the sort function?
