There are some custom categories I've had to add for myself to use when I'm using ShotLister as an AD - D/N, BG Reqs, Vehicle Reqs, etc. Right now, adding custom categories is only available shot-by-shot, and it would be good to be able to add them at the scene level so they can be blanketed to all shots in the given scene (it also leaves less room for me to miss adding them for a particular shot).
