Tagging with the Sorter

Quick question and I might be missing something obvious: Is there a way to add tags to an item I’ve dragged onto the sorter without having to do so once that item has been transferred to DT?

I know this can be done with info added via Take Note, but often I just drag images or PDFs and would like to add a few tags when I do so. I’ve looked around and can’t seem to figure out how to do it if it is possible.
