At risk of reiterating myself again, what Chris describes above is how professional engineering groups do their libraries. Every company I’ve worked for has a vetted parts list and the PCB layout library includes only those parts. The symbols and footprints are married to a part number. Under no circumstance would someone choose, say, an NPN transistor from a library and then later match it to a footprint and to something that can be ordered. The chance of an expensive fuck-up happening is way too high.
