[rules-users] cannot copy guided decision table

I tried to copy a guided decision table in kie workbench 6.0.1.Final It created the new decision table, but the generated drl (which can be viewed from the 'source' tab) cannot be validated, because the generated rule names are the same with the copied decision table. For example, copying the guided decision table: guided_decision_table.gdst to rules2.gdst will not change the generated rules names, they will still be: rule "Row 1 guided_decision_table". Is there something I can do about it ?
