For the 50 200 migration tool to migrate the Ex Ref field

Currently when you migrate from Sage 50 to Sage 200, the reference and details field are migrated on the PL/SL transactions. However the ex ref value isn't migrated. It is lost in the ether. Can the migration tool be updated to migrate the ex ref value rather than lose it. Where to put it is the next question. Currently the details goes against the 2nd ref and the nominal narrative, so maybe one of these fields could accommodate the Ex Ref value.
