Expedition - Ref Des' of both silkscreen layer and assembly layer

I usually change the size of the silkscreen reference designators (ref des) and move rotate and/or move them around on that layer.  My question is: "Is there any way that the assembly layer ref des' corresponding to the silkscreen ref des's that I had changed automatically follow the silkscreen ref des' ?"  For example, I change the silikscreen ref des height to, I don't know, say 20.  How can I get the assembly layer ref des height to automatically 20 also?  Or if I rotate a silkscreen ref des, how can I get the assembly layer ref des to automatically rotate too?
