However, all reports can be generated from the command lline using the 'omnirpt' command, I would think that you could write a script, and use a variable in place of a date, with the knowledge that you normally need a Timeframe (start and Finish time) to report on, and the date is normally in the format of
yyyy/mm/dd hh:min
for example
omnirpt -report list_sessions -timeframe 2014/05/12 00:01 2014/05/13:23:59 -html -log C:\temp\May12.htm
