Chaning parameter roles (not using a operator)
I find very inconvenient that I cannot change the roles of the variables in a dataset after it has been imported into RM. The only way --- as I understand --- is to re-import the data (takes a lot of time if I have many variables that need to be manually set) or to use an array of operators (clogs the view for starters). Is it not possible to reopen the dataset in the "import wizard" after the data has already been brought to RM? It would be so much convenient to change roles using the GUI.
