Current LDraw library is indeed missing complete shortcuts with cables. Maybe it would be a good idea to add them!
In the meantime, you can create these shortcuts using LSynth (or LDCad!) and make them a separate ldraw file. To show them in your PLI and BOM, you can use LPUB subst command, as explained here: http://www.eurobricks.com/forum/index.ph...try1622253 (section 3.5)
