Display filter value on email reportes

Display filter value on email reportes

Hi,
I am using the Email Schedule to send out all my reports.
i use also the different date filters.
I need to find a method that in the email itself or in the description the date of the filter report will be written.
if I use the option to filter "last 30 days", for the user is very difficult to see what are the chosen dates.
any ideas?
