Is there a way to copy only the speed graph of a property in After Effects and apply it to another layer?

Question

In After Effects, a lot of my time is spent in the graph editor, and a lot of the motion I create is similar. I've used Ease and Wizz to use expressions to duplicate easing motion between layers, but sometimes the motion I'm working on is unsuitable for this technique.

Is there a simple way to just copy the speed graph of a key framed property in After Effects to another layer, leaving its basic position values intact? It seems like it would be a basic feature of the application.

Almost 4 years later, but if you're still looking for a solution, I think this is what you are looking:

http://aescripts.com/easecopy/

This script allows you to copy just the curve and leave every other value (position/scale/rotation/etc) intact.
