Would be great to be able to select a reporting period of 'Year to Date' that would run from the first day of the year to the current date. Same goes for Current Month etc.
Most reports seem to have a default reporting period of 24 hr resulting in a long rendering time for environments like mine with a lot of audit data. Ideally, within the UI, you should be able to set the default period to any time period (built in or custom) either globally or per report.
