Indexing Files by dragging and dropping

Greetings,

I have a simple question. Just don’t know what I am doing wrong. I am attempting to drag and drop files from the finder into the Sorter and wish to create an indexed file in Devonthink Pro Office, not a duplicate. I am pressing Command-Option when I do this, but I am still getting a duplicate instead of an indexed file. I can create an indexed file if I go to File and select Index in DPTO, but this is cumbersome, i.e. not as simple as dragging and dropping. What am I doing wrong?

You can’t index files with the Sorter.
