Referencing the expression of another layer

So i have a somewhat lengthy expression that will be applied to all transform properties of all layers in a project. i would like to be able to easily update this expression and have that update ripple through all elements using it. my question is: is there a way to dynamically copy the expression of another layer? does the expression field itself have a name that i can use to copy it?

i want to do something like this:

thisComp.layer("layer_name").transform.position.expression;

where "expression" at the end is whatever the name of the expression field is. any help would be greatly appreciated.
