Due to lazyness I have unfinished documents of my coin collection. I have now reach that point where I can't handle it anymore, and thought I could use Numista to add the missing SCWC numbers, instead of switching between four catalogues. I am now on L - Luxembourg, when I noticed that all catalogue number are L#. I don't even know this catalogue, but I would like to have the KM# shown as a default. Would this be possible, or do I have to enter all the 41 coin sheets one by one, just to get the KM#?
