Coming back to this, I'm all the way up to adding the pick to the Gizmo via the script... and I don't know how to go about it. Here are the Gizmo picks for a skill that has a Specialty:
The SpecHelper is something that lets me constrain the choices of which Specialties can be picked for that skill and then there's the Beam specialty. How can I add a new one from a script? Or is that something that is possible?
