Exporting sortkey/sortname work ok for individuals but for organizations it should honor the "/" that is used within RE and create a special sortkey/sortname putting what is after the "/" first and the remainder after a colon or something. Sorting organizations is impossible once you have exported them.
I agree with this enhancement. It is a pain to export and break apart the name. The other option would be to add a Sort Field and it can default and be changed.
