Analytics Software

I'm would like to disable the export functionality to Excel (to many statistics are done on excel spreadsheets with outdated data, trying to force users to make use discoverer for their queries instead of exporting the data and manipulate the data in excel) How can this be done? Is it possible to assign export possibilities to certain roles so only a limited user group can export to excel (or other filetypes like csv) while it is disabled for other groups?


thanks for your input.
