Quick copy short citations

I've found a threat from 2007 that asked this question, but did not have any updates until now, so I'll pose it here again:

Is there any way to quick copy 'short citations' of the kind used after the initial citation? I frequently use shift + drag to insert citations, but after the first one, I'd naturally like to only use short form. I haven't found a way to do this yet, is there one? Otherwise this would be a great and probably simple thing to add. Maybe using shift + alt + drag?
