Right now the fine weight is calculated automatically by Numista with the total weight of an object and the given fineness.
But for segmented objects, what we call bi- or trimetallic, it is not possible to do so because we don't have the weights of the individual segments.
Can we have a field to enter the fine weight manually in such fringe cases?
As an example a 25 Euro niobium coin N#457938
Right now we have a total weight of 16.50 g, but would need an additional 10 g outer segment + 6.5 g inner segment (in this specific case perhaps only the outer segment, since it is the only one with precious metal content) to reach the fine weight of 9.0 g silver.
