Update variable value for all derived classes at once

[mfigueirido]

When working with derived variables, obviously the main point is being able to have customised values for derived classes, but sometimes I'm finding myself that I need to make sure all of my derived classes have a particular variable set with a good default that can later be changed.

There's no way to update all Character's children at once when setting a variable value

Currently to do this I have to go to the each derived class and update the variables one-by-one. It would be nice if there was a way to change the variable in the base class and have it sync to all derived classes automatically. But this should be an option because by default you might not want this.
