Exporting a custom tree view tab of the standard Document item type

Hi,

I created a Query Definition whose results are displayed in a custom TreeView-backed tab of the standard Document item type. I set this up through the 'Set Tree Grid View Usage' action in the Tree View editor.

Now I want to export this setup to a package and apply it to other Innovator instances. I tried exporting the relationship type that was created by the 'Set Tree Grid View Usage' action but the custom tab does not appear when importing in other instances.

Any ideas what I'm missing or how else to accomplish this?

Thanks!
