title: Adobe After Effects: Keep "Expression-Relations" when duplicating multiple layers
body: <p>just wanted to ask, whether there is a way to keep the relations of expressions going when duplicating layers.
  E.g. I have two layers, "LayerA" and "LayerB". Now I have an expression going on in "LayerB" saying, that its position always equals the position of "LayerA".
  Now when I duplicate those two and get "LayerA 2" and "LayerB 2" I want the expression in "LayerB 2" to reference to "LayerA 2"'s position rather than "LayerA"'s position!</p>
  
  <p>While it is no problem to simply change the expression when there is only one of them, it gets quite hard when you have multiple expressions going on ...</p>
