How would you re-create "File > Duplicate" function? [previously "Save As..."]

I’m trying to avoid the main window.
I found a solution that seems like it should work but isn’t.

There is an “Export” button I can add to the Toolbar of the document I’m working on in DT.

Click Export, it gives the option to rename, and I can chose the DT Inbox that is installed on Finder.

The problem: it doesnt import. I have to drag something else in there for it to register, and import the files.
