[Zope] same object in different containers

Hi, I am interested in having the same object appear as the child of two different containers. These containers may distant from each other in the object hierarchy. In particular, I autogenerate a list of subtopics (child folders) for several areas of my website, but would like a certain folder to appear in more that one listing because it can be classified in multiple ways. Is there a way to accomplish this? Is there anything in Zope like a symbolic link? Thank you for any advice or hints that you can provide. Best Regards, gyro
