Create multiple images from default imagefield?

Currently, I'm trying to create a newsfeed that writes the node title across an imagecache created picture using a node CCK Imagefield as the base picture. This works well when uploading a new picture along with every node. Problem arises as I want the users to be able to create news without uploading a picture as well. Therefore I tried adding a default picture to the node type hoping that it would resolve the problem.

This doesn't work though, since Imagecache views the default picture of the node as one picture, and thus generates just one version of it (stored in files/imagecache/preset/imagefield_default_images), resulting in every news item without a unique picture getting the same text.

Is there a way to tell Imagecache to generate a new image for every node that has the default image as well?
