Custom image paths

Is there a way to override the image path used in Edge animations? I'm setting up a publishing workflow to allow multiple independent Edge animations to be put together into a singlepage app, but this variable in the _edge.js files makes it a bit hard:

var im='images/'

So far I'm just patching it to the folder where i've put the images.

If nothing exists yet, it would be nice if Edge could instead output something like:

var im=AdobeEdge.imagepaths["compositionid"] || "images/";

so we don't need to do ugly rewrites which might break in future updates.
