In this example file i put together, it creates 10 instances of an object, then creates 10 objects based on a nickname and puts them into a family.
When i try and use the "Pick instances with matched substring in family " command to effect all of the created objects, it only effects the last one.
But if i use the "Pick Nickname instances in family" it will effect all of them.
Is the "matched substring pick not working? Or more likely i'm using it incorrectly.
