My buiness unit has a design problem that requires a unique
solution.  When
     possible, we build multiple assemblies from a common PCB.  There
are unique
     design circumstances (particularly broadband filters) where a
component in
     one assembly might be a resistor and in another assembly might be
an
     inductor or a capacitor -- using the same circuit board and located
in the
     same schematic position in the circuit.  We want to find a method
where we
     can specify one component with one reference designator, that will
allow
     multiple component types to be placed (R, L, or C).  The only
standard I
     can find is a reference designator of 'E' which can be used for a
     "miscellaneous electrical part".

     Is there some precedent or solution that any of you have found that
allow
     multiple types of components to be placed in the same electrical
and
     physical location in a circuit & board?
