The current easiest way to do this is to open the verses, by click-dragging from inside of the first reference to inside of the last reference. From that resulting 'Text' window, you can Select and Copy As -> References.
When I try this, I have to move quickly or else the program thinks I am doing a long-click and gives a pop-up with instant details.
I usually ⌘+⇧+click a single reference and it will open all the references cited in that paragraph. Then, as Joel said, you can select the verses and Copy as References.
As I am trying this out it seems somewhat temperamental. I can get it to work some of the time, but not all of the time. Under what conditions should it always work? Does an intervening non-biblical reference break the chain?
I think the main restriction is that all the references must be in the same paragraph.
