Mass update cant trigger a workflow?

Mass update cant trigger a workflow?

Hello there,
Is this a normal Creator behaviour?
In a report, if I manually edit each data row, it will pass those changes to all other reports.
However, if I perform a Mass Update on a few data rows at once, the new data is not pushed to other reports.
Creator support said that a Mass Update can not be a trigger for a workflow. 
Is it correct?
