Cloud Analytics Reports not to be safed automatically

Right now within the Cloud Analytics section under reports whenever you open a report, go to edit mode and change a value, parameter etc. the report is safed automatically even if this change should not be permanent. E.g. I have a report defined in $. If I need to change it to € I open it, change the value and run it to get results in €, but this is only a temp thing. Next time I need it in $. Therefore only if I want to keep the changes there should be option to safe it actively by clicking a safe button. If not then the report should cancel all changes done and work as defined before.
