It is not possible to change the order of attributes in saved reports created out of one Report.
At saved reports created out of one master template, it is not possible to save under different names the same reporting but with different arrangement of the attributes for the output file.
Steps to Reproduce
Out of one template a report was saved under 3 names. If one of this report is generated and the attributes are rearranged and saved again. The changes in the arrangement of the columns is propogated to the other two reports.
This would enable to have one Report Template containing many information and the users can customize this template according to their needs (e.g. Change Sorting, Change Column order,...)
