What about pin number of such universal decals? If case of simple transistor
there is 6 possibilities of connection in the physical element. Even simple
diode is an a problem as my example shows, when I get Eagle imported module
for miniMELF package and polarization was inverted. There has to be a way to
tie case and symbol on schema to be not overwritten by settings from cvpcb,
what is currently possible (should allow to select module and mark in by
close padlock icon) - sometimes engineer knows what part will be on the
board at the design stage.

I am not telling about different version of some digital chips - the problem
is deeper as someone prefers same symbols for the same logic and someone
prefers every version in the library with separate symbol.
