How to change the transformation point in symbols?
In Illustrator, the transformation tool handily allows you to select the transformation origin:

In the above example, when you resize the image, it will resize from the center-right side (as the transformation origin has been set to the center-right).
However, when working with symbols this option disappears:

If I re-size this image, it will resize from the center-center. How can I control the transformation origin with symbols? I know I can break the symbol apart (so it is no longer a symbol), but I don't want to do this, just in case I need to update the design of the symbol.
I am using Illustrator CS6, but symbols have been around for a long time, so there must be a solution to control the transformation origin, as I can't imagine people struggled without being able to for the many years that symbols have existed.
