How do you clip new documents to an existing document?
It is possible to clip documents in a tray directly to existing documents in a file cabinet.
Search for the existing document in the cabinet. Click on the split view button to open a second pane.
Open your document tray in this pane.
Ctrl+click to select desired documents in the tray, then drag and drop them onto the existing document in the top pane. Click clip.
Drag the new documents into the desired order in the stack, and click the yellow ‘clip’ button in the upper right.
