Has anyone accomplished, say, adding SAE J1926 straight thread o-ring port feature to the hole wiz?  Required would be: (1) Pilot hole, (2) tapped hole, (3) 45° countersink, (4) 12° or 15° countersink, (5) spotface.  Each of these then with unique specs (according to the standard) for -2 up to -32 sizes.  Any thoughts on how to build this out?
