Thanks for the example.
That's not exactly what i was looking for but i do now understand what
you mean with function-specific footprint. You are right, we should
never do anything like this.
I thought something more like you have symbol without pin numbers same
as yours in the example. The footprint has ordinary numbers though.
I was looking for a way to link the pin depending their function e.g.
pin E -> pin 1 (pin in symbol -> pin in footprint), B->2 and C->3 and
for different a footprint maybe E->3, B->2, C->1 and so on.

I agree. I think the perfect solution would be to feed the pin numbers
back from the footprint into the schematic.

Although we could make more generic symbols and footprints where more
people would benefit from, I think to wait for a feature like this would
probably take ages.
