Opening DNGs from Lightroom as Linked Smart Objects in Photoshop

How can I export a DNG from within Lightroom to to create a new PSD file containing the DNG as a Linked Smart Object? Also I'd like to be able to then edit the Linked Smart Object (from within PS) in LR rather then in Camera Raw. All I can find in LR is Edit>Export as Smart Object but this makes an Embedded Smart Object and there is no way to covert it to Linked. And I have to edit it in Camera Raw which I never use.
