Could be a (little) problem due the way eeschema (at least at one time)
'desconstructed' the designator (i.e. simply took off the last
character). Maybe when the other subdesignator styles where added it
changed. Nothing particularily difficult to handle in any case.

While we are on it, for the new library format, I'd like to have custom
sub-designators for fixed part components. The problem is that while you
go U1A, U1B, U1C, U1D for IC and stuff, for relays (just an example) you
*should* use K1, K1-1, K1-2, K1-3 (first one is coil, following are
contacts). Of course K1A, K1B, K1C works as well but that's not quite
correct:P
