If I'm understanding your question correctly.

You could change the link from an entry to an item... for example. (And I'll use examples from my own port).

I could link you to:

"Invalid Item"  my item or to "Invalid Entry"  a specific entry within that item.

I can change the second link from an entry to a ritem. But I can't make the entry into a static item without changing the entire format and making it a new section in my port.

I can also link to a folder: "Invalid Item"  if I'd rather.

Does that help?
