Custom Atomic Weights

I was wondering if it is possible to modify the default atomic weights used in JChem? Our Japanese colleagues would like to use the Japanese standard atomic weights instead of the "standard" atomic weights. Thanks.

JChem currently supports the IUPAC standard elemental weights, but this feature request is already in our task list. We will support custom weights very soon, it is a high priority feature request. Would you like to switch between the alternative weight tables, or you just need your own version included?

Alternative tables would probably be sufficient. I believe the Japanese lab would like to use the Japanese standard table. -&
