thanks shadysue. it was just an idea.
Maybe you can, but I've never heard of it, IO've never seen it done and can't see how to do what you probably want. (That's doesn't mean it's not there!)
People in the forums sometimes halfheartedly say you can link to a similar in the file description, but I can only see that you could do it as a text link. Again, I could easily be missing something.
