You now have the ability to save a default filter on all reports and dashboards. You can set your default settings by going to any report and clicking on the filter drop down in the top right and clicking 'Make these settings my default'.
For example, you can set up your default settings to show the current month's data on all the reports and dashboards any time you open them up. Each report or dashboard can have a different default setting.
Clicking 'Reset' deletes your saved settings and runs the default report showing last quarter's data.
