UPDATE: Reading dialog_gendrill.cpp it seems that code which was intended to do this is present, but completely broken. I've partially fixed it (it now generates a drill file for each layer pair that has vias on it, but blind/buried vias also are plotted in the PTH drill file) and will be posting a patch once I've debugged a bit further.
