Not sure if this is what you want, but when you import an image you get an option to "link bitmap externally".
If you select that option, then instead of simply copying the current contents of the image into your Corel document it remembers where the image came from, and if at print time the image has been changed it will print the updated form of that image.
A minor annoyance is that it doesn't always seem to revise the on-screen representation when you update the image, which can be confusing, though it does in practice print the revised version. You also have to be careful not to delete or rename the image. It would also be very nice to be able to link to other .CDR files in exactly the same way but that does not seem to be possible.
