Can I change the position of the transform point location on an object that is on a layer within a movie clip symbol?

I want to change the transform point of several layers that I have within a movie clip symbol. I can move the transform point using the transform tool, but when I click away from that layer and then click back to it again the transformation point has popped back to the center of the object. I haven't tried doing any animations yet because I wanted to set the transform points first. For example on the arm layer of my character I wan to the transform point to be at the shoulder portion of the arm, not in the center. Out on the main stage I can move the transform points of objects around and they stay where I left them when I click away and then go back. Is it just not possible to do this with layers that are already in a movie clip symbol? If so, what should I do? Should I start all over and import the layers to the stage, make the transformation point changes on the stage and then turn them into a movie clip symbol?

Please help!

Thank you in advance!
