Option for "Last 30 Days"

I think this would be handy as well. I regularly find myself looking to gather a month's worth of data mid-month. The options at that point are use the previous calendar month (2 week old data), use the current calendar month (half of the data), or to manually choose dates. Unlocking a 30 day timeframe as well as choosing the scheduling interval instead of locking it to the report timeframe would both be timesavers.
