Question about Families

I'm trying to set a variable common to every object in the Families but I cannot find the option, since in the edit familes men� I can simply add and remove object from the family.

There is a way to accomplish my purpose? O.o

Ashley said he's goinf to implement family variable's as soon as possible. And family behaviors :)

I supposed something like that, but I guessed it was better asking ;)

However.. Thanks Ashley for your work! ^^
