Report Filter

Report Filter

Good morning, I am looking to create a report that shows all open tickets that have not been updated in greater than 3 days.  I got all the filtering down except the date, it only seems to allow me to define a specific date, it does not seem to allow "today" or something similar as the start date.  I can select today from the date picker, but in 3 days that will still show 11-5 rather than 11-8 as the starting point.

Hope this makes sense.
